Abstract
A one-way clutch comprises plural sprags to be arranged between an outer ring and an inner ring, a retainer holding the sprags in place, and a spring guided by the retainer to urge the sprags in wedging directions. The retainer comprises a cylindrical part provided with sprag windows, which serve to retain the sprags, and a flange extending from one of opposite ends of the cylindrical part in radial directions of the cylindrical part and provided with plural slits, and is formed of a resiliently-deformable material. The flange comprises large-diameter portions and small-diameter portions separated from each other by the slits. The large-diameter portions of the flange can be press-fitted in a flange-receiving slot formed in an inner peripheral wall of the outer ring by causing the large-diameter portions to flex owing to the resiliency of the retainer, whereby the large-diameter portions can be maintained in engagement with the flange-receiving slot.
