ABSTRACT:
A variable length steering shaft for steering mechanism of motor vehicles and including an external profile tubular member having a non-circular cross-section, an internal profile member arranged coaxially with the external profile member and having its end portion received in the external profile tubular member, the internal profile member being axially displaceable within the external tubular member, and a slide sleeve formed of a macromolecular material and arranged in the gap formed by the external and internal profile members for formlockingly connecting the external and internal profile members for transmitting a torque therebetween, with an outer circumferential contour of the internal profile member and the inner circumferential contour of the external profile tubular member being at least partially formed each of a plurality of following each other convex and concave sections with radii of the convex and concave sections being respectively located inside and outside of a respective profile member, and with the slide sleeve having surface portions alternatively engaging the convex sections of the internal profile member and the concave sections of the external profile member.
