Abstract
A ratchet one-way clutch comprises an inner race provided with recessed portions on the outer circumference; an outer race member arranged coaxially with the inner race, being provided with pockets on the inner circum-ferential side; a pawl member arranged for each of the pockets to transmit torque by being fitted into each of the recessed portions; and a biasing member for biasing the pawl member in the inner diametral direction to promote the fitting. For this clutch, an operating element is provided to relatively rotate with respect to the outer race member, and an elastic member resides inclusively between the outer race member and the operating element.
