Abstract
Excellent durability and reliability are provided and assembling work is made easy. The clutch retainerof the roller clutchis prevented from being displaced in the axial direction. It is prevented that part of the clutch retainerrubs the portion rotating together with the follower pulley, so that the heat generation during over-run is prevented. Accordingly, grease degradation is prevented, and durability and reliability are improved. In addition, the inner clutch ringof the roller clutchand the rollers are provided with a chamfered portion along the outer periphery at the end thereof in the axial direction. Accordingly, the rollersare positioned properly in the circumferential direction, while the inner clutch ringis easily installed on the inner diameter side of the rollers, and the assembling work is made easy.
