A winding device for a roller blind arrangement, in particular for a vehicle, which has a winding element having a longitudinal axis. The winding element is constructed to be rotatably supported about the longitudinal axis on a vehicle and to wind and unwind a roller blind web. The winding device further has a coil spring having an axially extending hollow space, wherein the winding element is connected to the vehicle by means of the coil spring and the coil spring enables a rotational movement of the winding element relative to the vehicle. In addition, the winding device has a rod element which is arranged in the hollow space of the coil spring for guiding the coil spring, wherein the rod element is constructed in such a manner that the rod element radially tensions the coil spring.
