Abstract

A one-way clutch includes a radially-outer annular member having an inner peripheral race surface, a radially-inner annular member having an outer peripheral race surface, plural torque-transmitting members interposed between the annular members such that they are selectively tiltable to first positions where they come into engagement with the race surfaces to transmit a torque and second positions where they come out of engagement with the race surfaces, a ribbon spring for biasing the torque-transmitting members in a direction that they come into engagement with the race surfaces, a cylindrical cage for holding the torque-transmitting members at predetermined angular intervals and controlling their tilting, and a pair of end bearings arranged between the annular members on axially opposite sides of the cage, respectively, and supporting the annular members in a concentric relation. The ribbon spring is arranged between the cage and the inner peripheral race surface.
