Roller-type one-way clutch

摘要

In a roller type one-way clutch (10) comprising: an outer race (1); an inner race (2) that is apart from the outer race (1) on an inner diameter side in a radial direction and concentrically arranged to allow its relative rotation; a plurality of rollers (6) that are arranged between the outer race (1) and the inner race (2) and transmit a torque between the outer race (1) and the inner race (2); and a plurality of block bearings (7) that are arranged between the rollers (6) and between the outer race (1) and the inner race (2), the roller type one-way clutch (10) is characterized in that a curvature in a circumferential direction of a bearing surface (11) of the block bearing (7) facing an outer peripheral surface (16) of the inner race (2) is higher than a curvature in the circumferential direction of the outer peripheral surface (16) of the inner race (2).
