摘要

A tree joining device, preferably on a steering spindle of a safety steering column, whose parts can be moved telescopically in the axial direction after a reaction threshold has been overcome, characterized in that at least one part of a tree or one zone or an element of the tree part (6, 15, 20, 24) is deformed, after applying a predetermined torque, so that the tree parts (1, 2, 1a, 2a, 1b, 2b, 1c, 2c) can be immobilized to each other with force and form closure, and in the course of the deformation the rotation angle necessary for the clearance compensation of the shaft parts is exceeded in order to generate an elastic return force which is greater than the torque that has to be transmitted.
