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.

1. A one-way clutch comprising locking elements each accommodated in each of pockets defined in an inner peripheral surface of an outer race, each of said locking elements being urged by a spring toward an outer peripheral surface of an inner race, thereby inhibiting the relative rotation of said inner race and said outer race relative to each other in one direction, and permitting the relative rotation of said inner race and said outer race relative to each other in the other direction, wherein each of said locking elements is formed with a partially columnar support projection and an engage portion comprising a convex curved surface, said support projection being swingably supported in and substantially in face contact with a partially columnar support recess defined in the corresponding pocket, said engage portion being in line contact with an outer peripheral surface of said inner race comprising a columnar surface. 2. A one-way clutch according to claim 1, wherein said outer race is formed integrally with a stator of a torque converter and supported on stator-supporting members with a pair of thrust bearings interposed therebetween, and said locking element accommodated in each of the pockets in said outer race is prevented from being fallen off by the thrust bearings.
