Abstract

A rocker arm assembly which has an anti-inversion part that prevents a support pin from inverting and, thus, ensuring proper orientation of the support pin, on which a rocker arm is rotatably mounted, is maintained. The anti-inversion part can be incorporated on the support pin, the inner sleeve or the outer sleeve and/or a combination of the support pin, the inner sleeve and/or the outer sleeve.
