ABSTRACT:
The present invention is intended to provide a one-way clutch provided with a retainer which requires no crimping work in spite of using a metal spring and is superior in reliability and durability.
In order to attain the object, the retainer is equipped with one ring-shaped portion having an outer circumferential surface to be fitted into the inner circumferential surface of an outer race, and the other ring-shaped portion having an outer diameter smaller than that of the one ring-shaped portion and having convex portions formed at constant intervals in the circumferential direction on the outer circumferential surface thereof, these two ring-shaped portions being connected with bar portions so as to form pockets each accommodating a roller between every two of the bar portions. A metal spring, which is equipped with a flange portion having concave portions on the inner circumferential side to be fitted over the convex portions formed on the retainer, leaf portions positioned in the pockets of the retainer, and convex portions having inner circumferential surfaces to be fitted over the outer circumferential surfaces of the bar portions, is fitted into the retainer.
