  Further, for example, the central joint member 51 is disposed at the center in the vehicle width direction of the closed cross-sectional space A of the front header 11 so that the vertical vibration of the front header 11 together with the longitudinal roof reinforcement 18 is effectively prevented. Although it is preferable in that it can be suppressed, the node members 51 and 52 are arranged at positions that do not overlap the center portion of the closed cross-sectional space A of the front header 11 in the vehicle width direction and the front portion of the front inclined roof reinforcement 18. However, it is possible to arrange the front header 11 in any number in any position in the vehicle width direction of the closed section space A.

  Further, the present invention is not limited to the configurations of the first to fourth embodiments. For example, although not illustrated, in the vehicle Vc of the fourth embodiment provided with the front inclined roof reinforcement 20, the front vehicle width direction roof rain is provided. A fourth embodiment in which the widening joint flange 15 </ b> W provided in the vehicle Va of the second embodiment may be provided at both outer ends in the vehicle width direction of the force 15, and the front inclined roof reinforcement 20 is provided. In the vehicle Vc, the inclined member 19 provided in the vehicle Vb of the second embodiment is provided in the vicinity of the joint portion T1 (near the corner portion) between the roof reinforcement 15 in the vehicle width direction and the roof rail 3. Good.

Furthermore, the present invention may be an upper body structure of a vehicle provided with both the widened joint flange 15W and the inclined member 19.
Specifically, a wide joint flange 15W may be provided on one outer side in the vehicle width direction of the front side vehicle width direction roof reinforcement 15 and an inclined member 19 may be provided on the other outer side in the vehicle width direction (not shown). Alternatively, at least one of the both sides in the vehicle width direction of the front side vehicle width direction roof reinforcement 15 may be provided with both the wide joint flange 15W and the inclined member 19 (not shown).

  Further, according to the present invention, as described above, the front inclined roof reinforcement 20 provided in the vehicle Vc of the fourth embodiment is disposed in a direction in which the vehicle rearwardly inclines, such as a letter C, in a vehicle plan view. However, it may be arranged in a narrower direction toward the rear of the vehicle, such as an inverted C shape in a plan view of the vehicle, or in parallel, and the direction in which the front inclined roof reinforcement 20 extends is not limited. .

  As described above, the present invention is, for example, a pair of left and right roof rails provided to extend in the vehicle front-rear direction at both left and right ends of a roof portion of a vehicle body, and a roof panel disposed between the pair of left and right roof rails. A front header disposed in the vehicle width direction at the front portion of the roof panel, an upper portion coupled to the roof rail, a front pillar extending downward, and an upper portion coupled to the roof rail behind the front pillar. A center pillar extending downward, a vehicle width direction roof reinforcement extending in the vehicle width direction between the pair of roof rails, and a front header and front pillars on both outer sides in the vehicle width direction of the front header. This is useful for an upper body structure of a vehicle including a front window.
