Retainer for rotating members

An assembly, comprising:

• a first shaft having an axis of rotation, an outer surface defining an outer diameter, a cavity defining an inner surface that defines an inner diameter of the first shaft and a groove having at least a portion open to the cavity;
• a second shaft having an axis of rotation and at least a portion with an outer diameter smaller than the inner diameter so that said at least a portion can be at least partially received within the internal cavity;
• and
• a retainer having a c-shaped body with a radial inner surface and a radial outer surface, the body includes a curved section received in the groove and a finger having a radial inner surface and a radial outer surface and having a least a portion that extends inwardly toward the axis in an at rest state of the finger and projects into the cavity beyond the inner surface of the first shaft with at least a portion of the radial outer surface of the finger being closer to the axis than the radial outer surface of the body, the finger being flexible and in the at rest state when not acted upon by a force sufficient to flex the finger, and the finger has a second state wherein the finger flexes outwardly away from the axis when acted upon by a sufficient force and the finger being resilient so the finger returns toward its at rest state when the force is reduced or removed from the finger, and wherein the body includes an extension that extends axially from the curved section and interconnects the finger and the curved section, and the finger has a forward facing surface and a rearward facing surface that both extend between the inner surface and outer surface and define a radial thickness of the finger, the rearward facing surface is axially spaced from the forward facing surface and the forward facing surface includes an inclined portion.
