Subsequently, when the turning force in the direction of X is release, the spring 5 is about to return to the initial winding state to rotate the inner ring 4 in the direction reverse to the direction of X, but the rolling element 8 is instantaneously moved in the space 9 to the narrow side by elastic force of the spring 10 to bite between the inner ring 4 and a wall forming the space 9, whereby the inner ring 4 is kept from being rotated in the direction reverse to the direction of X. Accordingly, long-life and low-cost mechanism can be obtained.
