In a saddle-ride type vehicle in which a cylinder head of a single-cylinder engine main unit has a front wall and a rear wall, an exhaust system being connected to the front wall and an intake system being connected to the rear wall, a joining surface of the cylinder head to a head cover is formed on a plane crossing a cylinder axis, the plane being inclined downward toward a front. Rotation axes of camshafts are arranged on the plane. An axis of a valve stem of a throttle valve is arranged on the plane. A curve cover curved so as to cover driven sprockets fixed to the camshafts is formed on one side in a vehicle width direction of the head cover. A drum housing box housing a throttle drum fixed to one end of the valve stem is arranged close to the curve cover.

Saddle-ride type vehicle

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.

Garbage separation and recovery machine for beach cleaning

An exhaust pipe connected to an exhaust port of an engine and an expansion chamber is disposed in the vicinity of the engine. A main tube is provided that extends rearwardly from a head pipe disposed at the front side of a main body. An engine having a cylinder extending upwardly from a crankcase is disposed under the main tube with an exhaust port open at the front side of the cylinder. A first exhaust pipe is provided that is connected to the exhaust port. A down tube is disposed on the center line in the left-right direction of the main body. The exhaust port disposed behind the down tube is deviatingly open at one side from the center line. The first exhaust pipe extends forward from one side of the down tube, and to the other side of the down tube, subsequently turns, and extends again to one side.

Exhaust structure of motorcycle

A motorcycle includes a head pipe arranged at a front portion of a body and configured to pivotally support a front fork; a main frame passing an upper side of an engine from the head pipe and extending towards a rear of the body; a rear frame extending towards the rear of the body from the main frame and supporting a seat at an upper side thereof; an air cleaner case at a lower side of the seat; and an air cleaner element arranged inside the air cleaner case and configured to clean air, wherein the rear frame includes a pair of left and right rear bodies of a plate shape which cover sides of the air cleaner case, and a plurality of cross members configured to couple the left and right rear bodies, and wherein each rear body is formed with a projection projecting towards an inner side of the body, and a receiving portion configured to fit the projection is formed on the air cleaner case.

Motorcycle

An arrangement structure for a radiator reservoir tank for a motorcycle that makes it possible to appropriately dispose a reservoir tank of a radiator in the vicinity of an engine. A main frame is provided that extends to the rear side from a head pipe disposed at the front of a main body. An engine is disposed under the main frame, the engine includes a cylinder extending upward from a crankcase with an intake port open at the rear side of the cylinder. A throttle body is connected to the intake port with a reservoir tank of a radiator being disposed in a space S above the crankcase, behind the cylinder, and under the throttle body.
