An object of the present invention is to provide a three-dimensional CAD-system for adding data about a drafting direction of a die to three-dimensional data about the part to be formed by that die, and a cost calculation system for calculating the cost of the part based on that drafting direction data. A three-dimensional model generation unit of a CAD system generates: a three-dimensional shaped model of a given part based on information coming from an input operation unit. A drafting direction data setting unit establishes drafting direction data when the input operation unit is operated to designate the drafting direction of the die for press molding, injection molding or the like of the part in question. A projected area calculation unit calculates a projected area S of the part on a plane perpendicular to the drafting direction of the applicable die on the basis of the three-dimensional model of that part and the drafting direction data involved. A depth calculation unit calculates a depth D of the part in the relevant drafting direction.

Three-dimensional CAD system and part cost calculation system

A saddle type, off-road vehicle, comprising a frame, an engine supported on the frame, at least one front wheel, a pair of rear wheels disposed on opposite sides of the frame, and a storage receptacle provided on the vehicle having at least a portion thereof positioned above the rear frame. The storage receptacle is positioned rearwardly of the major part of the frame and above the rear axle.

Saddle type vehicle having a storage receptacle

A saddle type, off-road vehicle, comprising a frame, an engine supported on the frame, at least one front wheel, a pair of rear wheels disposed on opposite sides of the frame, and a storage receptacle having at least a portion thereof positioned above the rear frame. The storage receptacle having at least a portion thereof positioned rearwardly of the seat and the storage receptacle having an opening defined in an upper surface thereof, including a lid means for opening and closing the upper surface of the storage receptacle.

A motor vehicle with a riding saddle has a frame including a main pipe employed as an air intake passage for supplying air to an air cleaner. The main pipe has an air inlet defined in its front end. An air guide member is disposed on one side of the main pipe for introducing external air into the air inlet, and a radiator for cooling a water-cooled engine is disposed on the other side of the main pipe.

Air intake system and cooling system relation for three-wheeled motor

A rear axle supporting structure in a three-wheeled motor vehicle equipped with a chain drive mechanism. A holder member having an eccentric bore is fitted in a pipe member which is fixed to the rear end of a swing arm, and a rear axle is inserted in the eccentric bore of the holder member. A brake caliper for braking a brake disc is connected to the holder member through a caliper supporting member concentrically rotatably with respect to the eccentric bore of the holder member. Adjustment of the drive chain is effected by turning the holder member, without affecting the positional relation between the vehicle body frame and the swing arm, without any inclination of the rear axle occurring, and while maintaining a constant positional relation between the brake disc and the brake caliper.

Rear axle supporting structure in three-wheeled motor vehicle

A rear suspension system for motor vehicles. Both leg ends of a gate-shaped swing arm which at its free end supports the central part of a rear axle are pivotably secured to a vehicle body frame, a tension rod is provided between the lower end of a downwardly extending swing link mounted near the free end of the swing arm and a portion of the vehicle body frame near and below the above pivoted point of the swing arm, and one end of a damper disposed between both legs of the swing arm in a position above the tension rod is mounted near and above the pivoted point of the swing arm, while the other end thereof is attached to the swing link. The rear suspension system can be mounted in a relatively narrow space, and even with devices of relatively large capacities mounted thereabout, it can exhibit its damping characteristics satisfactorily.

Rear suspension system for motor vehicles

A vehicle with at least one front wheel and two rear wheels comprises a rear cushion unit for use in damping repelling forces from the ground surface and other vibratory forces developed by chain driving and the like. The upper end of the rear cushion unit is supported at a position axially rearward of a main frame member of a frame structure, while the lower end thereof is supported at a position forward of a rear axle bearing member. On each side of the rear axle bearing member there is mounted either a sprocket wheel or a braking device. A chain adjustment mechanism of the rear wheel assembly is constructed in such a manner that the front end of the swing arm is pivotally connected to the frame structure via elongated holes located in a lower portion of the frame structure, the elongated holes allowing the front end of the swing arm to be adjustable in position in the longitudinal direction, so that the rear wheel assembly comprising the rear axle bearing member, a rear axle and the rear wheels is adjustable in position in the longitudinal direction.

Vehicle

A device for preventing intrusion of water, dust, etc. into drum brake of an automotive vehicle, wherein a labyrinth is formed at a fitting portion between the outer peripheral surface of a brake panel fixed to the vehicle body and the outer peripheral surface of a brake drum rotatable together with wheels, and wherein the labyrinthine grooves are made larger as they go toward inside, and the edges of the partition walls and the brake panel of the brake drum forming the labyrinth are bent outward for effective prevention of the dust, etc. from entering into the brake drum.

Device for preventing intrusion of water, dust, etc. into drum brake

An arrangement for indicator meters for automobiles, in which a speed meter and a tachometer are coaxially arranged in a front-and-back positional relationship in the lengthwise direction of the vehicle body so that they may be more readily observed with the least movement of eyes as well as from one and same direction. Also disclosed is an arrangement for the warning indicator devices, in which such warning indicators as turning directions, operating conditions of brakes, dynamo, and so forth are arranged in vacant space around dial plates for the speed meter and tachometer, and such warning indicator devices are accommodated in a cavity formed on the top raised portion of a steering handle column cover. Further, disclosed is an arrangement of a lamp to illuminate the dial plates and the indicator needles of the speed meter and the tachometer, in which the illuminating lamp is fixedly provided at a position in front of the dial plates so as to directly illuminate the dial plates and the indicator needles, and the lamp thus fitted is covered with the top raised portion of the steering handle column cover.

Indicator meters for automobiles and illumination therefor

A portion of the instrument panel which is adjacent to the steering wheel is protruded and in which portion a radio receiving device is fitted which includes station-number and frequency indicator means and control means for station selection and frequency adjustment. The indicator means are arranged in the front face of the protruded panel portion so as to enable the driver readily to take the indicator readings without the need of shifting his line of sight to any substantial extent. The control means are arranged in the protruded panel portion sidewise thereof, including, among others, a single control knob arranged in a position to be readily reached by the driver's hand for controlling operation.
