PROBLEM TO BE SOLVED: To provide a roller type one-way clutch in which the drag of a block bearing is reduced.SOLUTION: A roller type one-way clutch includes: an outer ring; an inner ring separated on a radial inner diameter side from the outer ring, and concentrically arranged in a relative rotatable manner; a plurality of rollers arranged between the outer ring and the inner ring, and transmitting torque between the outer ring and the inner ring; and a plurality of block bearings arranged between the rollers and between the outer ring and the inner ring. In the roller type one-way clutch, the curvature in a circumferential direction of a bearing surface opposite to the outer peripheral surface of the inner ring of the block bearing is larger than the curvature in the circumferential direction of the outer peripheral surface of the inner ring. |
