Abstract: A steering pinion (1) manufactured with finished toothing by cold or hot forming in the form of a one-piece coupling linkage between steering shaft (6) and rack (4) of a steering mechanism on a motor vehicle, wherein the steering pinion (1) is provided with a cylindrical toothed portion (3) having helical toothing on its outside and with a collinearly adjoining cylindrical journal portion, whose diameter is larger than that of the toothed portion and whose end portion contains a driver recess for connection of the steering shaft (6). A transition region between the root circle of the helical toothing and the journal portion (2) comprises at least two conical portions, namely a radially outer conical portion having a first cone angle (α1) (die angle), which is disposed between the tip diameter at the toothing end of the helical toothing and the journal portion (2), and a radially inner conical portion having a second cone angle (α2) (entrance angle) , which is disposed between the tip diameter at the toothing end and the root circle of the helical toothing.
