Abstract

The invention relates to a rocker arm for actuating at least one gas exchange valve in an internal combustion engine , comprising an elongated main body (2) having two side walls (4 , 5) connected by a crossbar (3), wherein a first end section (6) of the main body (2) has a thrust face (10) for a cam and a second end section (8) of the main body (2) has a contact surface (14) for a valve stem end of the gas exchange valve. The side walls (4 , 5) have bores (19) in a section (7) near the centre for pivotably movable mounting on a rocker arm shaft, the main body (2) has a profile in the shape of an inverted U ,the crossbar (3) has a roof -like elevation (17) in the section (7) near the centre , the crossbar (2) having at least one oil passage opening (18) in its longitudinal centre section (7a) and a sleeve (20) mounted in the bores (19) via which the rocker arm can be directly mounted on the rocker arm shaft.
