It drips from the lower end and is discharged to the outside of the storage section 4 from a water outlet (not shown). At this time, the upper end surface 7e of the reinforcing member 7 is connected to the lower end 1 of the waist reinforcement 6.
0, the water W leaking into the storage part 4 will not fall on the upper end surface 7e of the reinforcing member 7, and the water W will not enter into the gap between the reinforcing member 7 and the door outer panel 1. This eliminates the situation where the rust remains over the gap, and there is no longer any concern that the inner surface of the door outer panel 1 will rust. In addition, in this embodiment, the reinforcing material 7
The upper end surface of the foam resin sheet 7b (see Fig. 3)
This foamable resin sheet 7 is partially exposed.
Since the exposed part b is completely covered by the lower end 10 of the waist reinforcement 6, even if the foamable resin sheet 7b has hydrophilic properties, it will not leak into the storage part 4. The water W does not permeate into the foamable resin sheet 7b portion, and rusting on the inner surface of the door outer panel 1 due to the water W permeating into the foamable resin sheet 7b is reliably prevented.

It is transmitted and flows downward of the upper reinforcing member 17a. At this time, since the upper end surface 17e of the upper reinforcing member 17a is covered with the lower end 10 of the waist reinforcement 6, the water W does not fall on the upper end surface 17e of the upper reinforcing member 17a, and the water W does not This eliminates the situation where the water W enters the gap between the material 17a and the door outer panel 1 or penetrates into the interior of the upper reinforcing material 17a, and the door outer panel 1 becomes free from water generated by the water W. There is no risk of rust. And upper reinforcement material 1
Water W flowing down along the outer surface of 7a drips from the lower end of the upper reinforcing member 17a, and after being caught by the cover 12, it falls to the lower part of the storage section 4 and is stored from a water outlet not shown. It is discharged to the outside of section 4. In this case, since the upper end surface 17c of the lower reinforcing member 17b is covered with the cover 12, water W does not fall on the upper end surface 17c of the lower reinforcing member 17b, and accordingly, the lower reinforcing material There is no possibility that the inner surface of the door outer panel 1 corresponding to the door outer panel 17b will rust.

とになる。 Furthermore, in this embodiment, if the upper reinforcing member 1
If the reinforcing material 17 is arranged so as to straddle the embossing 11 without dividing the reinforcing material 17, as shown by the two-dot chain line in FIG. A gap 14 is formed between the reinforcing material 17 and the door outer panel 1 in the upper and lower parts. For this reason, emboss 1
There is a risk that the reinforcing material 17 in the upper and lower parts of 1 will become meaningless. On the other hand, according to the embodiment described above, the reinforcing material 17 is divided into upper and lower parts with the embossment 11 in between, but the lower end of the upper reinforcing material 17a and the upper end of the lower reinforcing material 17b are connected to the highly rigid embossed material 11. Since the door outer panel 1 can be placed close to the upper and lower surfaces of the embossing 11, sufficient tension and rigidity of the door outer panel 1 can be ensured at the upper and lower portions of the embossing 11.

で、それだけ、車体外板の張剛性が向上する。 As explained above, according to the vehicle body outer panel structure according to the present invention, the lower end of the waist reinforcement covers the upper end surface of the reinforcing material after heating, and the lower end of the vehicle body outer panel and the waist reinforcement Since the upper end of the reinforcing material after heating is held between the two, even if water such as rainwater or car wash water leaks into the storage area from the waist opening, the leaked water will not fall on the upper end of the reinforcing material. This eliminates the situation where water enters the gap between the outer skin of the car body and the reinforcing material and remains for a long period of time, and as a result, rust is reliably prevented from forming on the inner surface of the outer skin of the car body. can. Furthermore, even if the lower end of the waist reinforcement is separated from the vehicle body outer panel, the upper end of the heated reinforcing material is interposed between the vehicle body outer panel and the lower end of the waist reinforcement. Since the reinforcement and the reinforcing material are connected and extend along the outer skin of the vehicle body, the tensile rigidity of the outer skin of the vehicle body is improved accordingly.
