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.
