As described above, according to the vehicle roof structure of the present invention, a bead portion is formed on the roof panel member in the vehicle width direction, and the bead portion is connected to the roof side on both side edges via the joint member. Since the roof panel member is divided into a plurality of upholstered surfaces by the bead portion, it is easy to secure the upholstery rigidity, and it is possible to reduce the weight of existing reinforcements such as roof bows and to reduce the weight. , A frame structure that is continuous with the roof side members on both sides is formed, so that the rigidity around the roof portion can be improved.
