２４号公報参照）。1. Prior Art - As is well known, in a back door vehicle as shown in FIG. 4, the back door hinge IA of the openable back door
, the rear end 2 of the roof panels 2A overlapped with each other.
However, since the back door X has considerable weight, it is necessary to improve the supporting rigidity of the back door hinge IA with respect to the vehicle body. For this reason, conventionally, rigidity reinforcing means as shown in FIGS. 5 to 7 have been employed. That is, the symbol "2A°" in FIGS. 5 to 7 indicates a roof panel, and of the rear pillar outer panel 4A and rear villa inner panel 5A forming the rear side of the vehicle body, the upper rear end 5a of the rear pillar inner panel 5A The rear end 2 of the roof panel 2A is
The side end portion 3a of the rear roof rail 3A extending in the vehicle width direction along the line a is spot welded. Then, on the surface of the side end 3C of the rear roof rail 3A, there is a back door hinge I.
Join the reinforcement 6 which will be the board for mounting A in advance,
In order to reliably transmit the force from the back door X transmitted to the reinforcement 6 to the vehicle body, an upper roof rail 7 extending in the vehicle width direction along the rear roof rail 3A is installed at the upper rear side of the rear roof rail 3A and the rear pillar outer panel 4A. It is combined with the end portion 4a (Japanese Patent Application Laid-open No. 59-733
(See Publication No. 24).

The force is applied to the rear pillar inner panel 5A and rear villa via the roof panel 2A and upper roof rail 7.
Since the information is transmitted to the outer panel 4A, a car body structure with a "shirakari" feeling can be obtained, but with this structure, the rigidity is improved by the upper roof rail 7 extending across the entire width of the car, so the weight of the car increases. However, there is a problem in that the manufacturing cost of the vehicle body is relatively high.

A roof panel 2 is provided at the upper rear end 5a of the inner panel 5.
A side end 3a of the rear roof rail 3 extending in the vehicle width direction along the rear end 2a is spot welded as in the conventional case. The back door hinge 1 disposed on the surface of the rear end 28 of the roof panel 2 is attached to the surface of the side end 38 of the rear roof rail 3. Part 3a
This is reinforced by a hinge reinforcement plate 8 having a size that spans the upper rear end 4a of the rear pillar outer panel 4. That is, this hinge portion reinforcing plate 8 has its front and rear side portions 8a, 8b.

価の削減を図ることができる。Since the illustrated embodiment has the above structure, the external force transmitted from the back door to the back door hinge 1 is transmitted to each part of the vehicle body via the hinge reinforcing plate 8. That is, the external force transmitted to the hinge reinforcing plate 8 is applied to the side end 3a of the rear roof rail 3 that is combined with the hinge reinforcing plate 8.
Although it is directly borne by the upper rear end 4a of the rear pillar outer panel 4, the side end 3a of the rear roof rail 3 is directly borne by the upper rear end 5 of the rear pillar inner panel 5.
Since the rear pillar outer panel 4 and the rear villa inner panel 5 constitute the rear villa which is a strength member, the supporting rigidity of the hinge portion reinforcing plate 8 is extremely high. Therefore, in the structure of the illustrated embodiment, the mounting portion of the back door hinge 1 is secured by the small and large hinge portion reinforcing plate 8 extending from the side end 3a of the rear roof rail 3 to the upper rear end 4a of the rear pillar outer panel 4. By increasing the bending rigidity of the vehicle, it is possible to reduce the weight of the vehicle body and manufacturing costs.
