Abstract

Connecting element (10) retains cam follower (2), which actuates gas-exchange valve (4) of an internal combustion engine, on support element (6). Support element (6) has spherical end (7) on cylindrical section (22) and on which cam follower (2) is mounted, so as to be pivotably movable in the direction of gas-exchange valve (4) about center of rotation (9). Connecting element (10) has elastically deformable projections (21), which proceed from central webs (19), parallel to the pivot axis of cam follower (2) such that connecting element (10) is connected to cylindrical section (22) in a frictionally-engaging manner. Projections (21) are embodied as lugs (20) which angle away from central webs (19) and extend in a direction pointing away from cam follower (2), so that projections (21) are elastic in shape.
