<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive one-way clutch having simple structure reduced in the number of parts and assembling man-hours. <P>SOLUTION: A shaft-like inner ring 20 is coaxially housed inside a cylindrical outer ring 10, and the outer ring 10 and the inner ring 20 are arranged to be relatively rotatable, cam faces 14, 25 are formed to both of an end face 12 on one shaft end of the outer ring 10 and an end face 23, respectively, on the other shaft end side of the inner ring 20, a coil spring 30 axially extended is inserted between the outer ring 10 and the inner ring 20, and one end 32 of the coil spring 30 is made to abut on the cam face 14 of the outer ring 10. Further, the other end 34 of the coil spring 30 is made to abut on the cam face 25 while the coil spring 30 is constantly in contact with the outer peripheral surface of the inner ring 20 and a diameter thereof is partially enlarged by rotary torque inputted from the outer ring 10, the coil spring can contact with the inner peripheral surface of the outer ring 10. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
