Abstract
A one-way clutch includes an inner race; an outer racesurrounding the inner race; a plurality of rollersinserted between an outer peripheral surface of the inner raceand a plurality of wedge facesformed on the outer raceso that they are opposed to the outer peripheral surface of the inner race; and springsfor biasing the rollersin directions to bite into the wedge faces. In the one-way clutch, the outer racecomprises an outer race bodymade of a light alloy and surrounding the inner race, and roller-receiving memberswhich have the wedge facesand which are disposed on bottoms of a plurality of recessesin the inner race bodyand harder than the outer race body. Thus, it is possible to achieve a reduction in weight of the outer race, while ensuring the durability of a contact face of the outer race with the rollers.
