Abstract:
1. A roller type one-way clutch comprising: an outer race; an inner race that is apart from the outer race on an inner diameter side in a radial direction and concentrically arranged to allow its relative rotation; a plurality of rollers that are arranged between the outer race and the inner race and transmit a torque between the outer race and the inner race; and a plurality of block bearings that are arranged between the rollers and between the outer race and the inner race, wherein an outer peripheral surface of the inner race is formed as a curved surface with a predetermined curvature in a circumferential direction and a bearing surface of the block bearing is formed as a curved surface with a predetermined curvature in the circumferential direction, and wherein the curvature in the circumferential direction of the bearing surface of the block bearing facing the outer peripheral surface of the inner race is larger than the curvature in the circumferential direction of the outer peripheral surface of the inner race.
