Abstract
Abrasion powder from the clutch retaineris prevented from getting mixed into the grease used for lubricating the roller clutch, and the grease is prevented from becoming exposed to high temperatures, and so degrading too quickly is prevented in the grease. Specifically, a retaining pieceis formed at one end of the clutch retainerin the inner-diameter side portion thereof, and a retaining collar sectionis formed around the inner peripheral surface of the other end of the clutch retainer. The inner ringfor the clutch is held from both sides in the axial direction between the fitting portionat the tip end of the retaining pieceand the retaining collar section. Consequently, displacement in the axial direction of the clutch retaineris limited, so that the axially opposite end surfaces of the clutch retaineris prevented from coming in sliding contact with the sections that rotate relative to the clutch retainer, specifically the inside surfaces of a pair of collar sectionsof the outer ringfor the clutch.
