Roller device for a sun blind for a motor vehicle window

The arrangement has at least one roller blind element (2) that is wound onto a shaft (3) in the retracted state and has an extraction element on an extraction end (5). The side edges (6) of the blind element are guided in lateral rails of a roller blind guide frame in the deployed state. Each lateral edge encloses a guide rod (8) in one of the guide rails in a pocket-like manner and is movable along the length of the guide rod.
