Abstract
A self-locking mechanism has a driving member, a driven member, a stationary member, a lock holder and a number of lock elements. The lock holder encircles the driving member and the driven member. The lock holder has a support base and ribs extending from the support base. A lock element is coupled to the axial end portion of each rib. The lock elements are radially positioned between a radially outer surface of the driven member and the inner wall of the stationary member. The distance between the radially outer surface and the inner wall gradually decreases from a center to opposite circumferential sides. The maximum distance between the radially outer surface and the inner wall is greater than the diameter of the lock element, and the minimum distance is less than the diameter of the lock element.
