Abstract
A shaft comprises two parts. One of these two parts is tube-shaped, and the other is pushed into the tube-shaped part along a main axis. The two parts are fixed to each other for rotation about the main axis and connected to each other in a gliding way along the main axis, by a spline provided between the two parts. One of the two parts comprises a plurality of elongated teeth which are parallel to the main axis and whose cross-sections decrease from the first part towards the second part. Intermediate spaces between neighboring teeth are at least as broad as the teeth. The other of the two parts, at its circumference facing the first part, is made of plastically deformable plastic material, and a counter-profile into which the teeth engage is pressed in the plastic material by intrusion of the teeth during assembly of the two parts.
