<p><P>PROBLEM TO BE SOLVED: To provide a one-way clutch, quickly achieving the operation from the unlocking state of an outer ring and an inner ring to the locking state and the operation from the locking state of the outer ring and the inner ring to the unlocking state, and having good responsiveness. <P>SOLUTION: This one way clutch 10 includes the outer ring 11, the inner ring 12 and a roller 13, wherein the inner ring 12 is provided with a cam face 12a, and when both rings 12 are relatively rotated in predetermined directions, the roller 13 moves to a clamping part on the cam face 12 to lock both rings, and when both rings are relatively rotated in the reverse directions, the roller 13 moved to a loosely fitting part on the cam face 12a to unlock the rings. The one-way clutch includes: a pivot arm 20 supported on the inner ring 12 through a spindle 15 to be rotatable and movable in the radial direction only for a predetermined distance, to which the roller 13 is rotatably mounted; a spring means 17 for turning and energizing the pivot arm 20 so that the roller 13 moves to the clamping part; and a set spring 30 for energizing the pivot arm 20 outwardly in the radial direction. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
