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.In assembling operation,a clutch inner ring(21)is inserted halfway on the inner diameter sides of a plurality of rollers(26),and in this state the clutch holder(28)and clutch inner ring(21)are rotated relative to each other.This operation results in the clutch inner ring(21)being inserted to the last while simultaneously compressing a plurality of springs that press the rollers(26).This makes it easier to attach the clutch inner ring(21)to the inner diameter sides of these rollers(26)while optimizing the circumferential positioning of the rollers(26),thereby facilitating the assembling operation. |
