<p><P>PROBLEM TO BE SOLVED: To provide a one-way whose axial size can be reduced, and in which engagement between an inner ring and an outer ring can be released to run idle by a predetermined operation. <P>SOLUTION: The one-way clutch 1 includes the inner ring 2, the outer ring 3, a movable piece (roller 71) housed in a pocket positioned between the inner ring 2 and the outer ring 3, a release member 4 rotatably provided with respect to the both of the inner ring 2 and the outer ring 3 on the same axis, a first operation member (first operation part 61) engaged with or fixed with the release member 4, and a switching member 5 having a circumferential surface to rotate relative to the first operation member cooperatively with one of the inner ring 2 and the outer ring 3. The release member 4 has a release piece 41 disposed adjacently to one side of the circumferential direction to the movable piece, the first operation member comes in contact with the circumferential surface of the switching member 5, and the switching member 5 has a small diameter part 51 as the circumferential surface, and a large diameter part 52 with a diameter larger than the small diameter part 51. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
