A one-way clutch includes inner and outer races which define circumferentially arranged wedge-shaped spaces, and clutch-actuating rollers received in the respective wedge-shaped spaces. Load-bearing rollers are provided between the circumferentially adjacent clutch-actuating rollers. The biasing force applied to one of the clutch-actuating rollers from an elastic member is transmitted to the circumferentially adjacent clutch-actuating roller through the load-bearing roller disposed therebetween. The biasing force biases the respective clutch-actuating rollers toward the narrow ends of the respective wedge-shaped spaces, and biases the load-bearing rollers against a cylindrical surface of the outer race having its center located on the axis of the outer race. Because the biasing force is not transmitted through a retainer, no high dimensional accuracy is required for the retainer. Thus, the one-way clutch can be easily manufactured and assembled. Still, it shows high locking capacity.
