PROBLEM TO BE SOLVED: To provide a vehicle roof structure capable of adequately setting the joining strength of a joining part between a mounting face of a side outer panel and a flange of a roof panel in the longitudinal direction of a vehicle.SOLUTION: A vehicle roof structure 20 has a roof panel 24 extending along a vehicle width direction and a vehicle longitudinal direction between side member outers 40 arranged along the vehicle longitudinal direction on both sides of a vehicle upper part. A flange 24B which is arranged downward of a vehicle in the longitudinal view of the vehicle and curved in a projecting manner outwardly in the vehicle width direction is formed at an end in the vehicle width direction of the roof panel 24, and the radius of curvature at a curved section of the flange 24B is set to be changed in the vehicle longitudinal direction. A mounting face 40B is formed at an inner side in the vehicle width direction of the side members outer 40 downward of the vehicle, and the flange 24B is joined with the mounting face 40B by brazing. |
