Abstract
The invention concerns a cam follower including a tappet having a cylindrical outer surface centered on a longitudinal axis (Y1) and adapted to slide in a housing surrounding the tappet, a pin extending between two opposite ends along a transverse axis (X1) perpendicular to the longitudinal axis (Y1), a roller element movable in rotation relative to the pin around the transverse axis (X1) and adapted to roll on a cam, and an antirotation member for preventing a rotation of the tappet around the longitudinal axis (Y1) in the housing. According to the invention, the antirotation member is one of overmolded onto the tappet and the tappet is overmolded onto the antirotation member. The invention also concerns an injection pump for a motor vehicle, each having a cam follower. The invention also concerns a method for manufacturing a cam follower.
