A garbage separation and recovery machine for beach cleaning that has mobility and can perform a garbage separation and recovery work according to the situation is provided. The garbage separation and recovery machine has a drum type sieve body () that is freely rotatably secured to a vehicle body frame () towed by a vehicle, a driving gear () that is freely rotatably supported by the vehicle body frame () and secured to an axle () to which right and left wheels are secured, and a mechanism portion () for transmitting the driving force of the driving gear () to the drum type sieve body (). The mechanism portion () has a gear switching mechanism () for performing a switching operation between an automatic rotation mode in which the drum type sieve body () is rotated by the rotational force of the wheels () and a manual rotation mode in which the drum type sieve body () is released from the rotational force of the wheel () and allowed to be manually freely rotatable.

A cowling structure is provided for a motorcycle in which a radiator is disposed behind a front wheel of the motorcycle. The cowling structure includes a main cowling and a sub cowling. The main cowling covers a periphery of the radiator from the front of a handlebar. The sub cowling is provided in the rear of the cowling through a space. The sub cowling is separate from the cowling. The cowling structure allows wind to effectively hit a radiator, and reduces a force necessary for inclining a vehicle body at the time of cornering.

Cowling structure for motorcycle

A motorcycle is provided having an engine disposed between a front wheel and a rear wheel and functional components, e.g., a first radiator, a fuel pump, a rear shock absorber, etc., are arranged, as viewed from the side, on a circumference of a circle with a radius R corresponding to a distance from a crankshaft, serving as a center, to a corner of an oil pan, serving as a part of the engine most distant from the crankshaft, to concentrate the functional components of the motorcycle at positions substantially equidistant from the crankshaft of the engine whereby a mass concentration toward the vehicle body center of a motorcycle is achieved.

A hot starter cable extends from a hot starter valve and an end of the hot starter cable is connected to a hot starter lever provided in the vicinity of a handle so that the hot starter valve can be opened by operating the hot starter lever. It is possible to easily operate the hot starter lever while the operator always keeping a hold on the handle, so that the operability at the time of restarting the engine can be further enhanced. In addition, since the hot starter lever is present within the visual field of the driver, the hot starter lever can be securely operated.

A motorcycle frame includes a down tube structured to be light in weight and shaped to simplify radiator piping. The down tube extends diagonally downwards from a head pipe to a front of an engine. The down tube is formed of an angular cross section pipe, with a rib being integrally formed on a front surface inner side, extending vertically. A lower half of a rear surface section of the down tube is made into a tapered section. A space is formed between the tapered section and front sections of a cylinder head and a cylinder head cover of the engine. A water hose of a radiator and an exhaust pipe are arranged in the space.

In a motorcycle intake structure, an air cleaner is provided under a sheet and an intake passage is connected to an upper opening of the air cleaner. The intake passage is formed by the sheet, a rear fender and a side cover. An inlet port from the outside of the intake passage opens rearward in a upper rear portion of the side cover. This motorcycle intake structure forms a smooth intake airflow with reduced intake resistance and free from influence by dirt or other debris.

A structural layout of a motorcycle concerning a fuel tank, a fuel cock, a carburetor, and an engine in relation to a frame is provided. A downward projecting portion is provided on a bottom of the fuel tank towards the rear. The projecting portion extends in a space defined behind a cylinder head and a cylinder head cover of the engine and in front of a rear cross member of the frame. The downward projection is juxtaposed with a carburetor across a motorcycle body. The fuel cock is manually accessible from beneath the one of right or left main frames of the frame.

A frame of a motorcycle is designed to allow for a simplified layout of an intake passageway. The frame includes left and right main frames. Rear ends of the left and right main frames are connected to upper parts of left and right pivot plates. Upper parts of the pivot plates have left and right upwardly extending sections jutting up higher than the rear ends of the main frames. A rear cross member is suspended between the left and right upwardly extending sections. An upper surface of the rear cross member supports a rear section of a fuel tank. A rear shock absorber bracket is provided on the rear cross member for supporting an upper part of a rear shock absorber. A space is defined beneath the rear cross member. An intake passageway, including a carburetor and a connecting tube, as well as an exhaust pipe and the rear shock absorber, are arranged in this space.

To provide an air cleaner fitting structure for a motorcycle that can form an ideal frame line without being limited by the position of the internal combustion engine and the fuel supply system, which can bring about favorable maintenance conditions. In an air cleaner fitting structure for a motorcycle having a vehicle frame in which a pair of right and left center frames extending downward, connected to a mainframe extending rearwards from a head pipe, and having an internal combustion engine arranged in front of the center frame below the main frame, a connecting tube for connecting an air cleaner arranged further rearward from the center frame and a fuel supply system at a front thereof is divided into front and rear halves. Furthermore, a division line between the front and rear halves of the connecting tube is located rearward from the center frame of the vehicle frame.

A tank cover attachment structure for a motorcycle includes a side portion of a fuel tank covered by tank covers and arranged behind a head pipe and linking the fuel tank and a seat, in that order. The support sections for the tank covers are provided on the seat and the fuel tank. By providing tank cover support sections on the seat, it is possible to directly attach the tank cover to a bottom plate of the seat, for example. Accordingly, it is possible to do away with components such as attachment stays, and it is possible to easily attach the tank cover.

A compact filter structure is provided having a cylindrical body disposed in the expansion chamber of a muffler. A tail pipe is inserted into the filter. The diameter of the filter is greater than that of the tail pipe. The filtering function of the body and the noise reducing function of the tail pipe are separated from each other. The filter structure can be formed in a compact construction which provides a large filtering capacity.

A fuel supply system in an off-road vehicle including front and rear wheels having wide tires, respectively, an engine mounted on a rear portion of a vehicle frame, and an exhaust pipe extending from the engine and disposed on one side of the engine transversely of the vehicle frame. The fuel system comprises a fuel tank assembly disposed on the other side of the engine transversely of the vehicle frame, and an air cleaner case disposed rearwardly of the fuel tank assembly. The vehicle frame comprises a plurality of welded pipe members. The fuel tank assembly has an outer peripheral flange supported at plural locations thereon by at least two of the pipe members of the vehicle frame. The fuel tank assembly has a cap for detachably closing a fuel inlet hole, the cap including a resiliently biased cover swingably mounted on an upper surface for covering a key slot from above. The fuel tank assembly comprises a main fuel tank disposed in a relatively low position and an auxiliary fuel tank disposed at a level higher than the main fuel tank and higher than a carburetor of the engine. The fuel supply system further includes a pump disposed in a fuel line interconnecting the main fuel tank and the auxiliary fuel tank. The fuel tank assembly has on a front wall thereof a cock positioned directly behind a driver's seat disposed substantially centrally in the longitudinal and transverse directions of the vehicle frame.
