| 摘要 |
The present invention provides a roller type one-way clutch comprising an outer race in which pockets provided at their inner surfaces with cam surfaces are formed, an inner race spaced apart from the outer race in a radial inner diameter side and disposed coaxially with the outer race for a relative rotational movement and having an annular outer peripheral track surface, a plurality of rollers disposed within the pockets to be engaged with the cam surfaces and adapted to transmit torque between the outer race and the inner race, a holder having a cylindrical portion and windows provided in the cylindrical portion to hold the plurality of rollers, and springs disposed within the pockets between the outer race and the inner race and adapted to bias the rollers to be engaged with the cam surfaces, and wherein the holder is rotatable relative to the outer race and biasing forces of the springs are transmitted to the holder via the rollers.
