Further, after spot welding, the second sealing material S2 is applied from the outside to the gap between the edge flange portion 48 of the cowl panel 40 and the opening edge 321r of the opening portion 321k of the lower panel 321x. As a result, when the first sealing material S1 foams due to the heat during baking coating, the first sealing material S1 and the second sealing material S2 are formed between the edge flange portion 48 of the cowl panel 40 and the inner panel 321 of the upper member 32. Double sealed.

<About the function of the body structure of the vehicle>
Rainwater flowing down along the surface of the windshield 20 passes through the opening portion 56 (see FIG. 3) of the cowl louver 50 and is received by the cowl panel 40, and is received by the water channel portion 44 of the cowl panel 40 on the right side of the vehicle and the left side of the vehicle. Be guided. Then, the rainwater is guided into the internal space of the upper member 32 from the openings 321k of the left and right upper members 32 (inner panel 321), and is drained to the outside of the vehicle from the drain port. As described above, as shown in FIG. 6, the end portion of the cowl panel 40 is covered with the opening 321k of the inner panel 321 (lower panel 321x) from above, and the end edge flange portion 48 of the cowl panel 40 is the lower portion. It is overlapped with the opening edge 321r of the opening 321k of the panel 321x from the outside in the vehicle width direction. Therefore, rainwater flowing through the water channel 44 of the cowl panel 40 does not leak inward in the vehicle width direction from the opening 321k of the inner panel 321 (lower panel 321x). Further, since the end edge flange portion 48 of the cowl panel 40 and the inner panel 321 of the upper member 32 are doubly sealed by the first sealing material S1 and the second sealing material S2, the cowl panel 40 and the upper member 32 (inner). Water leakage between the openings 321k of the panel 321) can be reliably prevented.

<Correspondence between the terms in the present embodiment and the terms of the present invention>
The cowl panel 40 described in the present embodiment corresponds to the groove-shaped member of the present invention, and the left and right upper members 32 and the pillar strut portion 14d correspond to the side wall member of the present invention. Further, the left and right edge flange portions 48 of the cowl panel 40 correspond to the flange portions of the right end and the left end of the groove-shaped member of the present invention.
