Abstract: In a one-way clutch comprising an outer race having an inner peripheral raceway surface and an inner race disposed in the outer race and having an annular outer peripheral raceway surface, the outer race and the inner race being radially spaced apart from each other and disposed concentrically with each other for rotation relative to each other, a plurality of sprags disposed between the outer race and the inner race for transmitting torque between the outer peripheral raceway surface and the inner peripheral raceway surface, an annular holder for holding the sprags, a spring member for holding the sprags with the holder and biasing the sprags in a meshing direction, and an annular retainer fixed to one of the inner race and the outer race to axially hold the holder, the retainer has a protruding portion protruding axially inwardly, and the protruding portion bears against the axial end portion of the holder.

Abstract: This invention is a one-way clutch directed to decrease the number of parts and the number of working steps and achieve a reduction in cost by changing the material and shape of a holder for the sprags of a conventional art one-way clutch, and is characterized in that the holder is made of a flexible material such as resin and by the utilization of the flexure thereof, the holder is fitted and fixed to an outer race.
