The axial displacement of the clutch retainer 28 of the roller clutch 10 is prevented. And, part of the clutch retainer 28 is prevented from rubbing the portion which rotates together with the follower pulley 7 to suppress the heat generation during overrun. Accordingly, grease degradation is prevented and durability and reliability are improved. During assembling, with the inner clutch-race 21 being inserted midway on the radially inner side of the rollers 26, the clutch retainer 28 is rotated relative to the inner clutch race 21. With this operation, the inner-clutch race 21 is completely inserted while the springs are simultaneously compressed to press the rollers 26. Accordingly, the circumferential location of the rollers 26 is properly maintained while the inner clutch-race 21 is easily installed on the inner diameter side of the rollers 26 and so the assembling process thereof become easy. <IMAGE> |
