Abstract
A one-way clutch designed to achieve a reduction in the number of parts and a simplification of assembly. The one-way clutch includes a retainer having a holding hole formed in a portion interposed between an outer race and an inner race to hold a sprag biting between the outer race. The retainer is provided with an elliptical flange urged against the inner periphery of a counterbore formed in the side of the outer race. Since the retainer holds the sprag with the holding hole, the structure of the one-way clutch is simplified. When the flange is pushed into the counterbore of the outer race, the portion of the major diameter of the flange presses the inner periphery of the counterbore, whereby the retainer is made integral with the outer race.
