Axial displacement of a clutch holder(28)constituting a roller clutch(10)is inhibited.And,a portion of this clutch holder(28)is prevented from rubbing against a portion that rotates with a driven pulley(7),thereby inhibiting the generation of heat during overrunning.This prevents deterioration of the greases,improving durability and reliability.Further,the peripheral edges of the axial ends of a clutch outer ring(25)and a plurality of rollers(26)constituting the roller clutch(10)are chamfered.This makes it easier to attach the clutch outer ring(25)to the outer diameter sides of these rollers(26)while optimizing the circumferential positioning of the rollers(26),thereby facilitating the assembling operation. |
