One-way clutch

摘要

A one-way clutch formed between an inner race and an outer race rotatable relative to each other for preventing the relative rotation thereof exceeding a predetermined limit. The permission and prevention of the relative rotation of the two races is accomplished by rollers contained in roller containing grooves formed in the inner race or the outer race. The opposite side walls of each containing grooves for holding the rollers in a predetermined state are formed by a roller holding member mounted to the inner race or the outer race. Engaging portions and engaged portions are formed on the holding member and the rollers, respectively.
