Abstract
A finger follower lever for actuating gas exchange valves of an internal combustion engine, having a lever body formed by two parallel side walls spaced apart by a transversely extending web. The web forms a first, joint socket end as a pivotable support for the lever, and a second end with a valve actuating surface. A cam roller is rotatably held between the side walls via a needle ring of a needle bearing. The cam roller projects partially via an aperture in the web for cam contact. The cam roller is narrow, and the needle ring projects beyond the cam roller at one axial end, and ends directly adjacent to a corresponding side wall. The aperture has a cross section defined by an overlap between a first, cam roller pocket with an extent corresponding to the cam roller in the axial direction, and a second pocket for the needle ring.
