摘要

A roller hydraulic valve lifter or similar cam follower mechanism wherein the follower of such an assembly or mechanism is provided with a pair of spaced apart struts to receive the opposed free ends of a roller shaft carrying a cam follower roller. Each free end of the roller shaft is provided with opposed flats parallel to the axis of the shaft to define abutment shoulders which engage the struts to limit axial movement of the roller shaft in the follower. Each strut is provided at its free end with a tang that is bent over to partly encircle a free end of the roller shaft whereby to retain the cam follower roller and roller shaft in unit assembly with the follower.
