ABSTRACT:
A retainer which is for a one-way clutch and is made of a synthetic resin so that the retainer includes a pair of annular portions, a plurality of column portions disposed at equal intervals along the circumference of the retainer and coupling the annular portions to each other along the axis of the retainer, roller pockets defined by the annular portions and the column portions, and elastic members integrally provided on the sides of the column portions, to which rollers housed in the roller pockets are moved when the one-way clutch is disengaged. The other side of each of the column portions is formed with an inner and an outer projecting parts projecting toward the former side of the neighboring column portion. The width of each of the elastic members gradually decreases from the butt thereof toward the tip thereof. The former side of each of the column portions is formed with stoppers for limiting the elastic deformation of the elastic members toward the former side of the column portion.
With this construction, the plastic deformation of the elastic member is avoided for a long period of time and the process and equipment for manufacturing the retainer can be made more rational and less expensive than those for the conventional retainer.
