ABSTRACT:
A retainer for preventing abrasion of a lock spindle of a lock mechanism by a torsion spring used to return the lock assembly the center position. The lock mechanism includes an axial spindle operably connected to the knob and the lock bolt for selective operation. The torsion spring which returns the lock assembly to the center or at-rest position is coaxially mounted about the spindle. The retainer includes tabs disposed between the spring and the spindle to prevent contact therebetween and thereby eliminate abrasion of the spindle by the spring which can result in premature failure of the lock mechanism.
