PURPOSE:To enable the change of creep rotation of a holder by simple structural change in a torque limiter with automatic reset function constituted in such a way that both annular parts provided in relation to bearing rings and a holder are fitted in contact and creep is generated between both of them to decelerate the rotation of the holder. CONSTITUTION:A roller 18 to be engaged with a cylindrical face 8 and a polygonal cam face 12 is integrated into a holder 16 provided between an inner and an outer wheels 1, 2, and a rolling element 28 is pressed in between the inner wheel 1 and an annular member 19 connected to the holder 16. An annular part 21 to be fitted to the annular member 19 is formed at a clearance adjusting ring 4 thrusted into the outer wheel 1, and the fitting faces of both parts are formed into axial inclined faces 22, 23. In this structure, the annular member 19 rolls in internal contact around the annular part 21 so as to generate creep, but a fitting clearance generating the creep is changed by advancing/retreating the clearance adjusting ring 4 to change the rotating speed of the holder 16. |
