<p><P>PROBLEM TO BE SOLVED: To realize a simplified torque limiter mechanism not using a torque limit groove in a one-way clutch. <P>SOLUTION: In this one-way clutch 30, a wedge region K formed between a clutch outer ring part 31 (outer ring member) and a clutch inner ring part 32 (inner ring member) straddles both cam faces 32a, 32a for each of pairs of cam faces 32a, 32a adjacent to each other out of a plurality of cam faces 32a, 32a. In the wedge region K, a lock region Kr is formed corresponding to one of the pair of cam faces 32a, 32a for bringing a roller 34 to a locked state, and a free region Kf is formed corresponding to the other of the pair of the cam faces 32a, 32a for bringing the roller 34 to a free state. The roller 34 is permitted to advance from the lock region Kr to the free region Kf under the condition that a prescribed torque limit value has been achieved. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
