Abstract

The invention proposes a modular-type assembled rocker arm (1) without a crossbar for a valve train of an internal combustion engine, said rocker arm (1) having two separate, substantially upright side walls (2) which are made out of a thin-walled lightweight material and comprise, on a centre-proximate section (3), bores (4) through which the side walls (2) are retained laterally spaced from each other on a tube member (5) which serves for mounting the rocker arm (1) on a rocker arm axle, said side walls (2) being additionally fixed on one end (6) by means of a U-like connecting clip (9) having a crossbar (7) arranged on a front end (8) of the rocker arm (1), and said side walls (2) being bridged on a further end (10) by an axle (11) equipped with a cam contacting roller.
