Abstract

The invention relates to a connection of a shaft to a driving element, wherein the driving element has an opening for the reception of the shaft, and at least one part of the opening and a part of the shaft positioned in the area of the opening have a polygon structure for the generation of an anti-twist protection, and wherein at least the shaft consists of a thermoplastic synthetic material and has a projection which makes possible a riveting between the shaft and the driving element on the basis of a plastic welding process, wherein at least parts of the opening in the gap area between the shaft and the opening are filled with welding waste.
