ABSTRACT:
A one-way clutch having an outer member and an inner member accommodates a plurality of rollers and compression coil springs therein. A plurality of seats are formed on the outer member to receive one end of the coil springs respectively thereon and each seat is formed in a circular-arc-shaped curve on a radially outer side of each seat. A projection directed toward the roller is formed on a radially inner side of each seat. Each compression coil spring is sandwiched between the outer curved surface and the inner curved surface. With the radially outer side of the seat being in the circular arc shape, the part of the outer member between the seat and the peripheral surface of the outer member can be formed thick, thus preventing a stress from concentrating thereon. The inner curved surface formed by the projection prevents the compression coil spring from interfering with the inner member.
