ABSTRACT:
Improved flexible ratchet teeth are provided for allowing relative rotational movement of one peripheral surface relative to an encompassing peripheral surface. Such teeth allow relative rotational movement in one direction of rotation only during which the ratchet teeth of one peripheral surface slide over the ratchet teeth of the other. The flexible teeth which may be disposed on either or both peripheral surfaces prevent distortion of the encompassing peripheral surface obtained in the prior art when ratchet teeth of solid construction are employed.
