ABSTRACT:
A rocker arm (1) or finger lever for a valve drive of an internal combustion engine is provided in which a guide bushing (7) is press-fit in a receptacle hole (2). The guide bushing (7) has a bore (9) in which an outer part (4) of a hydraulic play compensation component (3) is guided in a sliding manner. The guide bushing (7) has a radially inwardly directed projection (10) which holds a shoulder formed by a diameter reduction of the outer part (4) from behind or meshes in a groove of the outer part (4). This arrangement allows the hydraulic play compensation component (3) to be secured from loss using the press-fit guide bushing (7).
