Points to be solved by the invention When modularizing a car body as described above, in order to further improve the ease of attaching interior parts and functional parts, the car body roof is divided into a roof panel and a roof rail, and the body side assembly is divided into a roof panel and a roof rail. It is conceivable that a roof panel may be retrofitted to the roof rail, which is arranged in the shape of an opening in plan view on the upper part. However, since it is ideal for the vehicle body to be formed into an elag shell for aerodynamic reasons, the roof panel is formed into a curved surface shape. For this reason, when a roof panel is connected to a roof rail using a plurality of screws, all of the screws cannot be fastened in substantially parallel directions, resulting in poor assembly performance. Furthermore, if the screws penetrate the surface of the roof panel that is exposed to the outside of the vehicle, the waterproofness and appearance of the roof panel will deteriorate.

SUMMARY OF THE INVENTION Therefore, the present invention provides a structure for attaching a roof panel to an automobile, which can improve ease of assembly, waterproofness, and appearance.
