Abstract
A follower mechanism including an outer cup having a substantially cylindrical side wall, an annular lip portion disposed at a first end of the side wall, an annular ledge disposed on the side wall, the annular ledge being disposed in a plane that is transverse to a longitudinal center axis of the follower mechanism, and an anti-rotation device disposed on the annular ledge. An inner cup includes an annular lip extending radially-outwardly therefrom and a pair of shaft apertures, the inner cup being disposed in the outer cup so that the lip abuts the annular ledge of the outer cup as well as the anti-rotation devices so that the inner cup is non-rotatable with respect to the outer cup. A shaft is received in the shaft apertures, and a roller follower is rotatably received on the shaft.
