Abstract

See full text

A one-way clutch includes an outer race, an inner race which is spaced from the outer race in an inside diameter direction and arranged concentrically so as to be relatively rotatable, a plurality of engaging members which are arranged between the outer race and the inner race to transmit a torque, and a cage which retains the engaging members. The one-way clutch is provided with volute springs which urge the engaging members in the direction in which the engaging members engage with a cam face of the outer race or the inner race.
