Abstract
A cam follower including a plunger intended to execute a reciprocating movement in an exterior body. The plunger includes a plunger body having a cylindrical exterior surface, an anti-rotation device extending radially beyond the cylindrical exterior surface of the pusher body and engaging via a matching structure in the exterior body, a roller providing the contact with a cam, and a sleeve rotatably supporting the roller in the plunger body. The plunger body includes at least one lateral bore and the sleeve is inserted in the bore. In order to avoid additional components and assembly steps to constitute the anti-rotation device, the present invention proposes to use one end of the sleeve as the anti-rotation device.
