Abstract
Two sprag one-way clutch retainers each include sprag-receiving pockets for receiving sprags which are arranged along a circumferential direction and are equal in number to the sprags, and dummy pockets in the form of holes having both radially outer and inner ends open and arranged between the respective circumferentially adjacent pairs of the sprag-receiving pockets. One of the two retainers is an outer retainer positioned in a radially outer portion of the annular space of the sprag one-way clutch, and the other of the two retainers is an inner retainer positioned in a radially inner portion of the annular space. Each retainer has a junction formed by joining together two circumferential ends of a strip member to form the retainer.
