PURPOSE:To easily connect and disconnect a rotary shaft from a hub, and positively transmit torque by providing plural one-way clutch means one of which operates in the opposite direction, or plural clutch means which are engaged and fixed to each other when they are rotated in the opposite directions. CONSTITUTION:Plural clutch raceways 3, wedge-shaped notches 4 are formed on the inner peripheral surface 2 of a housing 1, rollers 7 are arranged in respective notches 4, and the roller are rotatably held by a holding ring 8. The direction of wedge tips 5a, 5b formed on the wedge-shaped notches 4a, 4b is reversed. Further, as a different constitution, two spiral rings 12a, 12b are arranged in the housing 1, and one end parts 13a, 13b are free and the other end parts 14a, 14b are fixed to the housing 1. Thus, the rotary shaft 10 is integrated into the housing 1 each time the rotary shaft 10 rotates on right and left, torque is positively transmitted, and the rotary shaft 10 can be easily connected and disconnected from a hub 11. |
