The telescopic shaft (1) has an inner section tube (2), a mid-section tube (3) and an outer profiled tube (4) which are arranged relative to one another. The length of inner section, mid-section and outer profiled tubes is changed slidably. A tension element (5) with axial slot (6) is axially immovably held with respect to the mid-section tube. An engagement unit (7) is connected to the inner section tube, for engaging the axial slot of the tension element to the boundary of a displacement path between the inner section tube and the tension element. An independent claim is included for drive shaft. |
