Abstract

A finger follower lever of a valve train, which has a lever body that is a pressed and punched component made of sheet metal and has a U-shaped cross-section with two largely parallel side walls. A roller rotatably mounted between the side walls on a pin. The pin is uniformly hardened and inserted at each end into a hole punched out of the side wall and is staked or caulked at the ends. To enable the holes to be punched out simultaneously in opposite directions of a relatively narrow lever body, at least one of the two side walls has, at least on the outside thereof, a flat recess in the region of the hole.
