A shooter for a snow remover has a shooter main body configured to be rotatably mounted on an auger housing of a snow remover for ejecting snow collected by an auger of the snow remover. A shooter guide is swingably mounted on a top end of the shooter main body to undergo swinging movement from an initial state thereof so as to allow adjustment of an angle of projection of the snow ejected from the shooter main body. A torsion spring has a single coil and is connected between the shooter main body and the shooter guide for urging the shooter guide to return to the initial state thereof. Vibration-reducing members are inserted into the single coil of the torsion spring so as to be in physical contact with one another and to surround and support an entire inner periphery of the single coil for reducing vibration and deformation in a radial direction of the torsion spring.

Shooter for snow remover

A shooter for a snow remover has a shooter main body and a shooter guide swingably mounted on the top end of the shooter main body by a hinge. The hinge has an interlocking member for preventing a pin member from falling out from the hinge. The interlocking member is formed from a wire material so as to have elasticity and has pressure parts for applying pressure to both ends of the pin member to retain the pin member in the hinge.

Working-machine steering apparatus includes an assist mechanism for reducing a force necessary for operating any one of left and right operating members. First and second cord members, connected to the left and right operating members, are wound on first and second pulleys in a U shape with given pre-slack. As a human operator operates any one of the left and right operating members, the corresponding left or right cord member is brought into close contact with the first or second pulley, so that rotation of a drive source is transmitted to the first or second pulley via a rotation shaft. The necessary operating force of the left and right operating members can be reduced using the rotation of the drive source via the assist mechanism.

Working-machine steering apparatus

An assist mechanism of a steering apparatus for a working machine includes right and left operational arm members for selectively engaging and disengaging right and left clutches. Right and left cam grooves are formed in the right and left operational arm members, respectively. A bar-shaped member has opposite ends disposed within the right cam groove and the left cam groove, respectively. A compression spring is disposed along a central axis of the bar-shaped member for urging the right and left operational arm members in directions away from each other.

Steering apparatus for working machine

An underwater scooter including a main frame on which are disposed two air tanks serving as a saddle area for the operator, a depth adjusting mechanism disposed to the fore of the air tanks, and a steering mechanism disposed to the aft of the air tanks. The depth adjusting mechanism can be swiveled freely around a vertical axis using a swivel mechanism, and moreover the angular displacement in this swiveling is transmitted by a swivel angle displacement transmission mechanism to the steering mechanism so that a rudder swivels around a vertical axis, and thus while the underwater scooter is traveling, the operator can ride upon the main frame and also adjust the depth of travel and direction of forward motion of the underwater scooter by manipulating the depth adjusting mechanism and steering mechanisms. Thus, the burden on the operator is reduced in comparison to that of the conventional types of scooters that tow the operator.

Underwater scooter

An underwater scooter includes a watertight vessel enclosing an engine disposed in the fore part of a cylindrically shaped main frame, a propeller disposed in the aft area, and a driveshaft passes through the interior of the main frame and transmits the output of the engine to the propeller. An operator rides upon air tanks disposed between the engine and the propeller on the main frame, so the burden on the operator can be reduced in comparison to that of conventional types that tow the operator. In addition, the propeller is disposed aft of the operator and also the exhaust gas from the engine is exhausted aft of the operator, so there is no risk of either the jet of water ejected by the propeller or the exhaust gas reducing the field of view or causing articles (goggles, etc.) worn by the operator to come off.

An underwater scooter is provided with an engine enclosed in a watertight vessel and an electric motor enclosed in the watertight vessel and connected to the output shaft of the engine, and a propeller disposed upon a main frame and connected to the output shaft of the motor to be driven and turned by at least one of the engine and the motor so as to propel the scooter. In other words, the scooter is a hybrid type having the engine and electric motor as the drive power of the propeller. With this, the operator can easily re-start, once stopped on the surface of the water or underwater. Moreover, since the propeller can be driven even by the engine, a distance of travel is elongated with less increased weight, when compared to the case that the propeller is driven solely by the engine.

Hybrid-powered underwater scooter

Underwater vehicle

A self-propelled operating machine has a power source, a hydraulic CVT for varying power outputted from the power source, and a transmission mechanism connected to the hydraulic CVT for transmitting power outputted from the hydraulic CVT. A stand is mounted between the transmission mechanism and the power source so as to enclose the hydraulic CVT. The stand has an oil passage through which hydraulic oil of the hydraulic CVT flows. A cooling fan cools the oil passage of the stand to thereby cool the hydraulic oil of the hydraulic CVT flowing through the oil passage. The cooling fan is disposed between the power source and the hydraulic CVT so as to be enclosed by the stand.

Self-propelled operating machine

A walk-behind working machine includes a motive power source, right and left transmission shafts, and a clutch for transmitting motive power from the source to the shafts. The transmission shafts are disposed in alignment with their respective ends butting against each other. The clutch includes a driving cylindrical member rotationally mounted around the transmission shafts. The transmission shafts have first grooves formed on their outer peripheral surfaces while the cylindrical member has second grooves formed on an inner peripheral surface thereof. The clutch further includes balls disposed between a space defined by the first and second grooves. The first groove is of substantially V-shaped configuration. The first groove has a leading end positioned between the ends of the transmission shafts.

Walk-behind working machine

A power transmission system for use in a snow-removing machine has a drive shaft having a first end for supporting a snow blower having a forward end and a rearward end. The drive shaft has second end disposed opposite the first end and for extension from the forward end of the snow blower. An auger transmission is connected to the second end of the drive shaft and has an auger shaft for undergoing rotation in accordance with rotation of the drive shaft. An auger is mounted on the auger shaft for rotation therewith. An overload protecting mechanism is disposed between the snow blower and the auger transmission for preventing application of a power overload between the drive shaft and the auger.

Power transmission system for snow-removing machine

An overload protecting device assembled in an auger transmission is disclosed as including a worm wheel having its side wall formed with a plurality of wheel-side protruding segments, a boss member engaging with the wheel and fixedly coupled to an auger shaft for non-rotating relationship, and a slide washer having a plurality of wheel-side projections facing the wheel-side protruding segments. When the auger shaft encounters a torque exceeding a given value, the worm wheel and the boss member are enabled to rotate relative to one another. As the wheel-side projections ride on the protruding segments, the slide washer is moved in a direction opposed to the worm wheel. A washer detection switch detects such a movement to produce a detection signal to forcibly stop the operation of an engine.

Overload protecting device for snow removing machine

A chute structure for a snow removing machine includes first and second chutes connected through a hinge to each other. The hinge includes first and second hinge plates connected together by means of a connecting pin. The first hinge plate has a tubular portion through which the connecting pin extends. The length of the tubular portion is substantially equal to the width of the first chute. The second hinge plate has first and second plates. The first plate has an opening formed therein. The opening of the first plate is aligned with an entrance of the tubular portion. The second plate has an opening formed therein. The opening of the second plate is aligned with an exit of the tubular portion. The second hinge plate has a cover portion extending between the first plate and the second plate. The cover portion is integral with the first and second plates. The cover portion covers the tubular portion. Provision of the cover portion prevents snow from being discharged from around the hinge.

Chute structure for snow removing machine

A snow removing vehicle has a vehicle body frame and a snow removing member connected directly to a front part of the vehicle body frame for removing snow from a ground surface. The snow removing member has a generally arc-shaped portion curved concavely rearward from the front part of the vehicle body frame. A single wheel axle is rotatably mounted on the vehicle body frame and is disposed in a widthwise central portion thereof so that the vehicle body frame is pivotally movable about the single wheel axle. At least one wheel is mounted on the single wheel axle. A pair of operational handles are connected directly to a rear part of the vehicle body frame so that upward and downward movement of the right and left operational handles relative to the ground surface pivots the vehicle body frame relative to the single wheel axle. When the operational handles are moved upward during removal of snow by the snow removing member, the vehicle body frame and the snow removing member pivot about the single wheel axle so that the front part of the vehicle body frame is inclined downwardly relative to the ground surface and both the driving wheel and a lower end portion of the snow removing member contact the ground surface or a surface of the snow and a chord of the arc-shaped portion extends generally perpendicular to the surface of the ground.

Snow removing vehicle

In a power-associated hand carrier including a body frame on which a wheel and a motor for driving the wheel are mounted, a manually operated forward drive control member for enabling the motor to produce power assist for moving the hand carrier in the forward direction and a manually operated reverse drive control member for enabling the motor to produce power for driving the hand carrier in the backward direction are both provided on the distal end portion of one of two handlebars extending from a rear portion of the body frame obliquely upward in a rearward direction of the hand carrier. The hand carrier having such forward and reverse drive control members is easy to handle and can exhibit good mobility when used in a relatively narrow working area or when moving over rough or angulated ground surfaces.
