SUMMARY OF THE INVENTION A flange 21 of a roof panel 20 and a flange 24 of a roof side rail 22 are provided.
In the case of spot welding with the electrode 26, one electrode of a spot gun (not shown) is inserted into the groove 27 and welding is performed. Therefore, the electrode easily interferes with the groove edge of the groove 27, and the workability cannot be reduced. Absent.

Further, it is necessary to apply a paint seal 32 as a sealing material to the end portion of the flange 21. The end of the flange 21 is located at the corner of the groove 27 on the roof side at the bottom of the groove. There is also a problem that it is difficult to perform sealing material filling work because of blind spots.

Further, when rainwater, car wash water or the like enters the groove 27, this water stays in the groove 27 and the paint seal 3
If the two parts are wetted and there is even a small seal failure part, water may penetrate into the overlapping portion of the flange 21 and the flange 24 and enter the vehicle interior.

Therefore, the present invention facilitates the joining work between the roof panel and the roof side component member, and also facilitates the filling work of the sealing material into the joined portion, and furthermore, the sealing can be completed perfectly and the quality and the quality can be improved. An object of the present invention is to provide a roof molding mounting portion structure that can further improve reliability.

Further, a terminal portion of the roof side flange projects to a molding terminal receiving portion which is formed stepwise in an oblique manner on an upper portion of the outer panel of the roof side component member, and a sealing material is provided below the projecting terminal portion. Since the filling is performed, the filling operation can be performed by guiding the sealing material filling tool in sliding contact with the terminal portion, and furthermore, when the terminal portion is viewed from the side, the peripheral portion thereof is free space. The sealing material filling operation can be easily performed, and the sealing material filling defect is not induced.

In addition, a gap is formed below the end portion of the roof side flange between the molding terminal receiving portion formed stepwise in an oblique manner and serves as a sealing material pool, so that the sealing material is sufficiently filled and held. It is possible to improve the sealing property.

Further, since the end portion of the roof side flange projects toward the side of the molding terminal receiving portion which is formed stepwise in an oblique manner and is overhanging, the lower side is filled with a sealing material. The water that has flowed into the roof side flange can be guided downward from the end portion to the oblique molding terminal receiving portion, so that water can be prevented from staying in the sealing material filling portion, and the sealing property can be further improved. Can be improved.

According to the second aspect, a substantially horizontal shelf portion is formed below the terminal portion of the roof side flange at a position lower than the joining flange portion. The gap on the side, that is, the capacity of the sealing material pool can be enlarged, the filling amount of the sealing material can be increased, the sealing material can be stably held, and the sealing performance can be further improved.

In addition, since the sealing material filling tool can be placed on a substantially horizontal shelf and guided to slide, the filling operation can be performed stably, and the sealing material filling operation can be further improved.

According to the third aspect of the present invention, since the water cut piece bent downward is provided at the end of the roof side flange, a seal material pool can be defined on the back side of the water cut piece, and the seal material is filled when the seal material is filled. This suppresses the flow and improves the retention of the sealing material.Moreover, the water flowing down from the end of the roof side flange can be guided down by this drainage piece, ensuring that water directly hits the sealing material on the back side of the drainage piece. Therefore, the sealing performance can be further improved.

According to the fourth aspect, the roof molding is fixed from the vertical wall of the roof-side flange forming base to the molding terminal receiving portion, and the roof molding is substantially attached to the outer surface of the roof panel and the outer surface of the outer panel of the roof side component. Since they are mounted flush with each other, a sense of continuity is obtained in the outer surface shape from the outer panel to the roof panel, and the appearance can be improved.
