More Information
Summary:The object of this invention is to improve a one-way clutch incorporated into an engine of a motorcycle to remove the need for switching a gear to a neutral position in the case of push walk of vehicle. A one-way clutch 60 of this invention comprises a clutch inner wheel 62, a clutch outer wheel 65 coaxial with the clutch inner wheel 62, a cam surface 62b formed on the outer periphery of the clutch inner wheel 62 or the inner periphery of the clutch outer wheel 65, a roller (rolling member) 64 arranged between the clutch inner wheel 62 and the clutch outer wheel 65 and rolling on the cam surface 62b, and a compression spring (biasing member) 66 biasing in a direction of narrowing the roller 64 by pressure of the clutch inner wheel 62 and the clutch outer wheel 65 along the circumferential direction. The clutch is characterized by comprising an centrifugal weight (restricting member) 63 which restricts, in low-speed rotation, the movement of the roller 64 in the biasing direction within the range where the roller 64 can freely roll, and releases the restriction in the case of a predetermined number of rotation or more.
