It is difficult to form the outer flange, and it is easy to cause flange cracking. Therefore, as shown in FIG. 4, a notch portion b is provided in the flange portion a of the rear quarter panel outer in this portion, and a patch member c is applied thereto to cope with the flange cracking, and a front edge corner of the trunk room opening portion. The trunk drip flange e in the vicinity of the rear panel d is formed by extending the side end of the rear panel d.

[0004]

In the conventional structure shown in FIG. 4, the corner portion of the trunk drip flange is formed by extending the side end of the rear panel.
Not only the yield of the rear panel is extremely deteriorated and the rigidity of a single unit is lowered, but also the rear panel, which is a relatively large part, is difficult to form the corner R of the trunk drip flange corner portion, so it is mounted inside the corner portion. It is difficult to reduce the size of the trunk lid hinge.

[0005] The present invention has as its main object to address the above conventional problems.

[0006]

According to the present invention, a conventional patch member is enlarged, and a corner flange portion serving as a mounting surface of a lower edge corner portion of a rear window glass and a front edge corner portion of a trunk room opening are all formed. The first feature is that the trunk drip flange corner portion to be formed is constituted by the above-mentioned patch member, and a drooping extension portion hanging down below a rear outer end of the patch member is integrally formed, and the drooping extension portion is formed. The second feature of the present invention is that it is bonded and fixed to the rear quarter panel inner and the rear arch inner.

[0007]

According to the above, the extension of both ends of the rear panel is not required, and the yield of the rear panel and the rigidity of the rear panel are improved, and the patch member is much smaller than the rear panel. Can be made smaller than before, and the size of the trunk lid hinge can be reduced and the volume of the trunk room can be increased.

[0008] Further, by joining and suspending the hanging extension to the rear quarter panel inner and the rear arch inner, it is possible to improve the yield of the rear quarter panel inner and increase the rigidity of the trunk drip flange corner.
