Abstract: A hard-top vehicle is provided with a roof structure which includes at least one roof part and a rear-window part and which can be pivoted, via a positive-control device supported such that it is fixed to the bodywork, from a closed position in which it bears in the region of the front windscreen frame and covers the rear-passenger-compartment region into an open position, towards the tail-end region of the vehicle. In the open position, the roof structure can be lowered into a folding-top compartment in the region of a tail gate supported via a pivot pin. The tail gate is articulated via its pivot pin, on an auxiliary frame. For its part, the auxiliary frame is supported, via a pivot pin, on the bodywork in the lower vehicle end region.
