Abstract
The invention relates to a winding shaft for a roller blind device with a winding tube (2) and a torsional tensioning device (7) that, with a first end (7a), is coupled to the winding tube (2) in a manner that enables it to rotate in relation thereto. The torsional tensioning device (7), at least with a second end, is coupled to the winding tube (20 so that it is rotationally fixed and axially displaceable in relation thereto.
