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. |
