摘要： A one-way clutch includes poles and springs accommodated in pockets defined in an inner peripheral surface of an outer race. The poles are urged toward an outer peripheral surface of the inner race by resilient forces of the springs, thereby inhibiting the relative rotation of the inner race and the outer race relative to each other in one direction, and permitting the relative rotation of the inner race and the outer race relative to each other in the other direction. Each of the poles has a partially columnar support projection, and an engage portion comprising a convex curved surface. The support projection is swingably supported in and substantially in face contact with a partially columnar support recess defined in the pocket. The engage portion is in line contact with the outer peripheral surface of the inner race comprising the columnar surface.
