PROBLEM TO BE SOLVED: To provide a reverse input cutoff mechanism which can be inexpensively manufactured with a simple structure and be miniaturized.SOLUTION: Fixed side members (2), (26) have peripheral surfaces (2a), (26a) for receiving a coil spring. Input side rotating members (4), (22) have peripheral surfaces (4a), (22a) for receiving coil springs and are rotatably mounted in the fixed side members (2), (26). Output side rotating members (8), (30) have peripheral surfaces (8a), (30a) for receiving coil springs and are rotatably mounted in the fixed side members (2), (26). The coil springs (12), (20) are configured to include a part press-fitted in the peripheral surfaces (4a), (22a) of the input side rotating members (4), (22), a part brought into contact by a small pressure with or fitted to peripheral surfaces (8a), (30a) of the output side rotating members (8), (30) with a small gap, and a part press-fitted to peripheral surfaces (2a), (26a) of the fixed side members (2), (26). |
