ABSTRACT:
A bearing retainer including a flange having a front surface and a rear surface, a hub extending from the front surface and having an exterior surface configured to receive and support a looped extension spring and having an interior forming a bearing pocket, and at least one resilient finger initially extending from the rear surface and having a curve so as to extend toward and beyond the front surface and including at least one retainer tab extending from a surface opposite the hub and positioned on the rear surface side relative to the flange. The resilient finger is configured to be deflectable from a free position toward the hub in response to a deflection force to enable a portion of the resilient finger including the retainer tab to be inserted through an opening in a wall and to substantially return to the free position upon release of the deflection force such that the wall is held between the retainer tab and rear surface, thereby securing the bearing retainer within the opening.
