<p>PROBLEM TO BE SOLVED: To provide a one-way clutch which can suppress that an inner ring and an outer ring are relatively decentered by a simple constitution.SOLUTION: A one-way clutch 1 comprises: an inner ring 2 and an outer ring 3; a plurality of sprags 5 arranged between an external peripheral face 2a of the inner ring 2 and an internal peripheral face 3a of the outer ring 3; and a cage 6 which holds the sprags 5 at prescribed intervals along the circumferential direction. In the one-way clutch 1, when the inner ring 2 and the outer ring 3 relatively rotate in one direction, the sprags 5 are brought into states that they are engaged with the external peripheral face 2a of the inner ring 2 and the internal peripheral face 3a of the outer ring 3, and when the inner ring 2 and the outer ring 3 relatively rotate in the other direction, the sprags are brought into states that they are released in the engagement. The one-way clutch 1 comprises an annular eccentricity suppression member 8 which suppress that the inner ring 2 and the outer ring 3 are relatively decentered in idling states.</p> |
