Abstract
A friction clutch includes a clutch cam which is movable with respect to a clutch hub in a center axis direction of a transmission shaft. The clutch cam has a release rod which penetrates through the clutch hub and is extended toward the pressure plate. An adjustment bolt which is provided at the pressure plate and is configured to restrict a moving range of a clutch cam in the center axis direction is disposed to face an end portion of the release rod which is closer to the pressure plate.
Claims10
A back torque reducing device of a friction clutch comprising:
- a pressure plate configured to cause a drive plate, which is engageable with a clutch outer part to which rotation of a crankshaft is transmitted, and a driven plate, which is engageable with a clutch hub and is rotatable integrally with the clutch hub, to contact each other with a pressure;
- a clutch cam movable with respect to the clutch hub along a center axis direction of a transmission shaft;
- and
- a contact member provided at the pressure plate and configured to contact the clutch cam;
- wherein the clutch cam is configured to move toward the pressure plate along the center axis direction when a back torque is applied to the transmission shaft and press the contact member to cause the drive plate and the driven plate to be away from each other;
- and
- wherein the clutch cam has an extended portion with an end extending closer to the pressure plate than the clutch hub, and the contact member is disposed to face the end of the extended portion which is closer to the pressure plate.
