Abstract
A worm gear for a worm gear mechanism of a motor vehicle steering system includes a carrier body and a multiplicity of teeth with tooth surfaces. The teeth point radially outward and the carrier body is formed from a plastic including reinforcement fibers and has a multiplicity of ribs with rib surfaces which point radially outward from a central encircling ring-shaped web of the worm gear. The teeth are applied to the ribs of the carrier body by injection molding, and the reinforcement fibers are oriented, wherein the multiplicity of reinforcement fibers, in terms of their orientation, follow the adjacent rib surfaces of the carrier body and/or the adjacent tooth surfaces of the teeth.
