<P>PROBLEM TO BE SOLVED: To obtain a steady clutch operation for a long period of time with a simple structure even under a state of use wherein the direction of a reverse input torque and input torque comes in a corresponding manner, with respect to the reverse input prevention clutch which is of a type wherein the output side member is locked against the reverse input torque. <P>SOLUTION: It is so arranged that, out of the output side members 4, an inner ring 3 is formed of a metal plate, the inner ring 3 having a cam surface 3b that receives a load from a roller 10 at locking, while an inner ring protrusion part 3a, being provided with the cam surface 3b, bows in a radial direction at locking to alleviate the impact. This restrains the occurrence of vibration to smoothly rotate the output side members 4 even when input torque and reverse input torque are simultaneously applied in the same direction causing repetition of release of locking and re-locking. Further, its structure is simple, and no substantial labor is required for its assembling and maintenance. <P>COPYRIGHT: (C)2013,JPO&INPIT |
