ABSTRACT:

BACKGROUND OF THE INVENTION
In the case of some exterior door knob constructions, the lock cylinder does not exactly mate with the exterior knob due to slight variations in manufacturing tolerances. As a result, there is a small amount of movement between the lock cylinder and the knob that is undesirable. A lock cylinder retainer that eliminates the undesirable movement would be welcome by manufactures and consumers.
SUMMARY OF THE INVENTION
A lock cylinder retainer comprises an annular portion and a rectangular portion extending from the annular portion. The annular portion is configured to engage a lock cylinder core and the rectangular portion is configured to engage a pin housing associated with the cylinder core. The annular portion includes a front edge and a flange extending radially inwardly from the front edge and the rectangular portion includes a front surface, a pair of parallel side surfaces and a top surface. The front, top and side surfaces cooperate to partially enclose the pin housing.
