Abstract
In a one-way clutch, a plurality of sprags held by a retainer in a swingable manner and forced by a spring in one direction are interposed between an inner ring and an outer ring. A pair of end bearings are slidably fit to the outer ring on both sides of the retainer between the inner and outer rings. A pair of annular retainer plates each having a plurality of pawls around an outer periphery are provided so that the annular retainer plates support the end bearings in opposite axial directions when fastened to the outer ring by the pawls. An annular recessed portion is concentrically formed on an annular part of each annular retainer plate. When the retainer plates are mounted in position, the annular recessed portion of one of the retainer plates is opposite both a radially inside part of one end face of the outer ring and a radially outside part of a corresponding end face of one of the end bearings, and the annular recessed portion of the other retainer plate is opposite both a radially inside part of the other end face of the outer ring and a radially outside part of a corresponding end face of the other end bearing.
