The invention relates to a longitudinal member for a chassis (2) of a road vehicle (1), wherein the longitudinal member (8) is designed as a drawbar shaft of a preferably rigid, V-shaped drawbar (4). The cross-sectionally profiled longitudinal member (8) has an upright thin-walled support wall (31) which runs in the longitudinal direction of the member and has a transversely directed support wall (32, 33) arranged on the upper and/or lower longitudinal edge thereof, wherein the upright support wall (31) has a plurality of wall openings (34, 35) and wall webs (36, 37) arranged in between. The upright support wall (31) has a lattice structure (10) with wall openings (34, 35) and with narrow wall webs (36, 37) between the wall openings (34, 35), wherein at least some wall webs (36, 37) are inclined obliquely with respect to the longitudinal direction of the member and in different directions.
