The mechanism has a nut disposed therein which is accessible through an opening formed in the housing. The retainer has a body portion positionable across the opening for serving as a cover therefor and nut locking device provided on the body portion and extendable into the opening. The retainer is securable in any of a plurality of angular positions relative to the nut to permit the placement of the nut locking device in constraining relation thereabout to lock the nut in substantially any desired rotational position so as to prevent its inadvertent loosening during operation. |
