Follower mechanism

A follower mechanism movable within a bore along a longitudinal center axis of the bore, comprising:

• an outer cup having an inner surface and an outer surface defining a substantially cylindrical side wall, an annular lip portion disposed at a first end of the side wall, and an annular ledge disposed on the inner surface of the side wall, the annular ledge being disposed in a plane that is transverse to a longitudinal center axis of the follower mechanism;
• an inner cup including an annular lip extending outwardly therefrom and a pair of shaft apertures, the inner cup being disposed in the outer cup so that the lip of the inner cup abuts the annular ledge of the outer cup and is non-rotatably fixed thereto by the annular lip of the outer cup which abuts the lip of the inner cup;
• a shaft having a first end and a second end, each of the first end and the second end being disposed in a corresponding one of the shaft apertures;
• and
• a roller follower rotatably received on the shaft such that a portion of the roller follower extends axially outwardly beyond the annular lip portion of the outer cup.
