ABSTRACT:
A telescopically moving structure (1) comprising a nut (2) mounted in a rotationally fixed manner in relation to a frame part, a spindle tube (3) with an external thread in engagement with the nut (2), which spindle tube (3) furthermore has an internal thread (4) with the opposite direction to that of the external thread, which internal thread (4) is in engagement with a non-rotational spindle (5) provided with an external thread, the spindle tube (3) being connected in a rotationally fixed manner, but in the axial direction in a slidable manner to a driving shaft (6), wherein the driving shaft (6) has an essentially polygonal cross section with a perimeter forming two opposite longitudinal tracks for engagement with torque-transferring rolling bodies which are journalled in a bushing fastened in the spindle tube (3) to thereby enable transfer of a large torque without the risk of seizure between the driving shaft (6) and the spindle tube (3).
