摘要： A clutching system comprises a lever mechanism portion and a clutch mechanism portion. The lever mechanism portion comprises a push lever. The push lever comprises a cam surface. The clutch mechanism portion comprises a push rod. The push rod comprises a cam follower. A Belleville spring functions as a clutch spring. The cam surface and the cam follower are formed such that a lever ratio of the push lever at a pivot start position is larger than a lever ratio of the push lever at a pivot finish position. The Belleville spring is formed such that a force required to move the push lever at the pivot finish position is smaller than a force required to move to the push lever at the pivot start position.

摘要： In a motorcycle having a V-belt type continuously variable transmission, a resin washer made of a nylon resin is interposed between a boss fixed to a moving sheave half of a secondary sheave and a spring bearing member. The boss contacts the spring bearing member through the resin washer, whereby the moving sheave half is restricted to a Top position, in which a spacing between it and a stationary sheave half becomes maximum. In this manner, the maximum speed is not changed by exchange of the V-belt, the V-belt does not slip or become considerably abraded or deteriorated, and noise generation is suppressed.

摘要： Abrasion of a V-belt in a belt type continuously variable transmission accommodated in an engine unit of a motorcycle is suppressed. A V-belt wound around and contacting a primary sheave and a secondary sheave 72 is at least partially formed from a resin. A plurality of grooves aligned at a predetermined pitch in a radial direction are formed on sheave surfaces of the primary and secondary sheaves. The average pitch P(mm) of the grooves is P≦−0.08K×10−3+0.18, where K(Hv) indicates surface hardness of the sheave surfaces.

摘要： A downsized power unit equipped with a clutch operation-assisting device that reduces operation force of a clutch lever. The clutch operation-assisting device includes a push shaft and a first rotation plate that is rotatably supported by a support plate and connected to a clutch wire, and slides the push shaft by rotation. The first rotation plate and a second rotation plate are connected by gear. The second rotation plate is rotatably supported by a bearing member fixed to the support plate. A spring unit that provides assisting force in a direction to disengage a friction clutch is connected to the second rotation plate by pin. The spring unit, as seen from a shaft direction of the push shaft, is disposed so that an extension direction of an auxiliary spring does not pass through a rotation center of a pressure plate.
