In order to achieve the above object, according to the first aspect of the present invention, there is provided a roof panel in which left and right side edges are connected to a roof side rail formed by welding an outer member and an inner member to a closed cross-section. A glass sunroof fixed at the periphery of the longitudinally long opening formed in the center of the roof panel, a front guide frame extending in the left-right direction of the vehicle body and connected to the front edge of the opening and the left and right roof side rails, and the vehicle body A rear guide frame extending in the left-right direction and connected to the rear edge of the opening and the left and right roof side rails; and at least connected to the left and right roof side rails extending in the left-right direction of the vehicle body so as to cross the middle part in the front-rear direction of the opening one intermediate guide frame, extending in the longitudinal direction of the vehicle body, the front guide frame, the rear guide frame and the intermediate guide frame A reinforcing frame that is connected to the position and the right end position of the left end, the front guide frame and the intermediate guide frame between, and a rear guide frame and the intermediate guide transverse sliding on each inter-frame rotatably supported has been glass sunroof Left and right sunshades that cover the lower surface of the glass, and left and right sunshade storage portions that are formed between the opening and the left and right roof side rails and that store the sunshade that opens the lower surface of the glass sunroof , a front guide frame, a rear guide frame, and An end portion of the intermediate guide frame is sandwiched and welded between an inner surface of the inner member of the roof side rail and an inner end of the gusset welded to the lower surface of the inner member. A vehicle upper body structure is proposed.

According to the configuration of the first aspect, since the glass sunroof is fixed to the periphery of the opening which is formed in the center of the roof panel and which is long in the longitudinal direction of the vehicle body, not only can the feeling of opening of the passenger compartment be enhanced, but also it extends in the lateral direction of the vehicle body. A sunshade divided into left and right is arranged between the front guide frame, the rear guide frame and at least one intermediate guide frame so as to be slidable left and right, so that the lower surface of the glass sunroof can be selectively opened and closed with at least four sunshades. By doing so, it is possible to individually illuminate the occupants seated on the left and right of the plurality of rows of seats, thereby enhancing comfort. Moreover, the front guide frame, the rear guide frame, and the intermediate guide frame are connected to the left and right roof side rails, and the front guide frame and the rear guide frame are connected to the front and rear edges of the roof panel opening. Therefore, it is possible to avoid a reduction in vehicle body rigidity due to the opening formed in the roof panel.

In addition, since the front guide frame, rear guide frame, and intermediate guide frame that extend in the left-right direction of the vehicle body are integrally joined by the left and right reinforcement frames that extend in the front-rear direction of the vehicle body, not only the rigidity of the vehicle body is effectively increased, but also the subassembly As a result, it is possible to connect the front guide frame, the rear guide frame, the intermediate guide frame, and the reinforcement frame assembled in advance to the left and right roof side rails, thereby contributing to an improvement in assembly.
