Next, a procedure for connecting the upper body 2 and the lower body 3 in the automobile body structure of this embodiment will be explained.

The Atsupa body 2 is placed over the lower body 3 from the upper position, and the lower ends 9 of the upper front pillars 7a, 7a,
9 is the lower front pillar 7b, the upper end 10 of 7b,
Insert each into 10. Accordingly, the lower side connecting portion 4a of the upper quarter panel 8a is placed on the upper side connecting portion 4b of the lower quarter panel 8b at the same time as the insertion, and the mating surface 19 of the lower side connecting portion 4a and the upper side connecting portion 4b are aligned. Surface 20 can be surface-joined on a horizontal surface. As a result, the positioning of the upper and lower body 2 and the lower body 3 in the longitudinal and lateral directions by the upper and lower front pillars 7a and 7b and the mating surface 1
9 and 20 can be accurately performed at once and as a whole. In addition, when placing the lower side connecting part 4a on the upper side connecting part 4b, the dimension between the lower side connecting parts 4a, 4a is the same as that of the upper side connecting parts 4b, 4b.
Since it is slightly larger than the distance between each flange 17,
18 does not interfere with the corresponding mating surfaces 19 and 20.

Next, the upper body 2 and lower body 3 are joined together by bolting. When tightening bolts on the rear side, bolt holes 21 in the flange 17 of the upper quarter panel 8a and bolt holes 2 in the lower quarter panel 8b
1, and the bolt holes 21 of the flange 18 of the lower quarter panel 8b are aligned with the bolt holes 21 of the upper quarter panel 8a, respectively. At this time, by utilizing the elasticity of the roof 1 of the atsupa body 2, the upper quarter panel 8a can be easily brought into alignment with the lower quarter panel 8b by slightly moving it back and forth while maintaining the overall positioning state.

Thereafter, bolts 31 are passed through these bolt holes 21 and screwed into the nuts 22 of each quarter panel 8a, 8b. Due to this screwing, the mating surface 19 of the lower side connecting portion 4a of the upper body 2 moves inward while surrounding the mating surface 20 of the upper side connecting portion 4b of the lower body 3. This movement also utilizes the elasticity of the roof 1. The upward flange 18 of the lower body 3 is attached to the inner surface of the lower side 40a of the inner panel 14a of the attachment body 2, and the downward flange 17 of the attachment body 2 is attached to the attachment surface 15 of the lower body 3.
b simultaneously contacts the outer surface of the upper side 41b. As a result, the upper quarter panel 8a of Atsupa body 2
and the lower quarter panel 8b of the lower body 3 can be fastened together according to the designed dimensions. As shown in FIGS. 4 and 5, adhesive bonding may also be used by interposing an adhesive 50 between the mating surfaces 19 and 20.

As described above, the Atsupa body 2 and lower body 3 can be positioned and fastened accurately and quickly, so the joining work itself is easy, and the workability of the fitting process for the vehicle interior, which can be performed prior to this joining process, is improved. It is possible to improve the 6th
As shown in the figure, the lower body 3 is common, and the upper body 2 has a different roof variation.
By combining these, it is possible to easily realize diversification of external designs.

Since the upper body 2 and lower body 3 are divided below the belt line a, the exterior design including the area around the rear window 49 can be diversified. Further, since the dividing line is set above the door hinge attachment portion 5 and the door lock striker attachment portion 6, there is an advantage that the quality of the door area can be stabilized.

The present invention can be configured in various ways other than those shown in the embodiments.

For example, in the above embodiment, the connecting plate material, which is a separate member from the inner panel and outer panel forming the quarter panel part, is used for the lower side connection part and the upper side connection part of the quarter panel part, but the inner panel and the outer panel are extended. The lower side connection part and the upper side connection part of the present invention can be constructed by doing so. Note that the shapes and specific configurations of these lower side connecting portions, upper side connecting portions, and reinforcements are not limited to those shown in the above embodiments, and can be appropriately designed as desired.

(Effect of the invention) According to the invention of claim 1, the rigidity of the upper and lower intermediate parts of the outer panel can be reinforced without performing spot welding, and the rigidity of the outer panel of the quarter panel part on the side of the upper body can be further strengthened. The outer panel can be reinforced by a box structure, and can prevent vibration and denting of the outer panel.

Further, according to the invention of claim 2, the rigidity of the upper and lower intermediate portions of the outer panel can be reinforced without performing spot welding, and the rigidity of the outer panel of the quarter panel portion on the lower body side is made into a more solid box structure. Therefore, the outer panel can be reinforced, and vibrations and dents in the outer panel can be prevented.
