Movable cover

The shroud (1) has an adjustable vehicle roof placed downward in a rear-side retaining space (3), where the shroud is formed as a roof box lid (5) and movable between a closed position (Gst) and an opened position by a hydraulic cylinder or a gas-filled support (20). The lid is connected to a rear cover (6) by a knuckle (10). A stopper (7) is provided between the lid and the rear cover for limiting angular movement between the lid and the rear cover, which is designed as a lever or suspension arm. A guide element (14) e.g. sliding device or unwinding unit, is provided at an end of the box lid.
