PROBLEM TO BE SOLVED: To prevent early breakage of a one-way clutch by restraining eccentricity of inner and outer rings by a retainer.SOLUTION: A one-way clutch has: a sprag 110 arranged between an outer ring 109 and an inner ring 106; a retainer 114 holding the sprag 110 by plural pockets bored at an annular part formed by forming a plate material into a cylindrical shape in a circumferential direction; and a spring 116 arranged between the retainer 114 and the sprag 110, and energizing the sprag to the outer ring 109 and the inner ring 106 in a meshing direction. The retainer 114 has: a first collar part 114e bent to project to an outside diameter side from the annular part; and a second collar part 114f bent to project to an inside diameter side from the annular part. The outside diameter of the first collar part 114e is made equivalent to a trajectory diameter of the outer ring 109, and the inside diameter of the second collar part 114f is made equivalent to a trajectory diameter of the inner ring 106. |
