Abstract
A one-way clutch has a plurality of engagement members disposed between an inner ring and an outer ring and spaced at regular intervals in a circumferential direction of the one-way clutch, an annular retainer having a cylindrical part with pockets for receiving the engagement members and a flange which is continuous with an axial end of the cylindrical part and protrudes radially outwardly, and an annular spring for urging the engagement members in a direction of engagement with the inner and outer rings. The retainer has at least one pair of engagement portions to be engaged with the outer ring, the paired engagement portions being located substantially symmetrically relative to an axis of the retainer. Each engagement portion is defined between two pockets and between two slits respectively connected to the two pockets and passing through the flange to the outside of the retainer. The flange in each engagement portion has an outer radius larger than that of a portion of the flange other than the engagement portions and larger than a radius of an inner surface of the outer ring.
