PROBLEM TO BE SOLVED: To prevent an inner cylinder of a torque limiter from slipping out of an outer cylinder. SOLUTION: In this torque limiter, a coil spring 3 is installed on the outer periphery of the inner cylinder 2 with an interference; its inner cylinder 2 is inserted into the outer cylinder 1; the front end of the inner cylinder 2 is allowed to abut on a projection part 7 formed on the inner periphery of the outer cylinder 1; an annular cover member 4 is arranged for blocking up a part between the inner periphery of the outer cylinder 1 and the outer periphery of the inner cylinder 2; its cover member 4 is prevented from slipping out of the outer cylinder 1; a support part 21 supporting an end part 17 of the coil spring 3 is arranged in the outer cylinder 1l; and torque transmitted between the inner cylinder 2 and the outer cylinder 1 is limited by sliding between the coil spring 3 and the inner cylinder 2. The rear part outer periphery 13 of he inner cylinder 2 and the inner periphery 14 of the cover member 4 are formed in a tapered shape of narrowing a diameter backward. COPYRIGHT: (C)2008,JPO&INPIT
