Abstract
A toothed rack has hollow sections and a longitudinal axis that extends parallel to a longitudinal direction and which in the hollow region includes a wall encompassing the longitudinal axis of the toothed rack in a circumferential direction and in at least a subregion comprises a toothing. In the circumferential direction spaced apart from the toothing, at least one local attenuation and/or holding edge is developed in the wall, which, with respect to the longitudinal direction of the toothed rack, extends at least over a portion of the length of the toothing next to the attenuation.
