行してしまう。Problems to be Solved by the Invention The connection between the roof site rail and the rear villa is achieved by slightly lapping and brazing the rear end of the outer roof side rail and the front end of the chaff ender, and in the same way, connecting the rear end of the outer roof side rail and the front end of the chaff ender. This is done by slightly lapping and brazing the end portion and the front end portion of the rear pillar inner, but it cannot be denied that stress concentration is likely to occur at the joint portion due to these brazing processes. Therefore, in order to increase the strength and rigidity of the joint part, it is sufficient to insert a reinforcement within the closed cross section in a required pre-stage length range centering on the joint part so as to partition the closed cross section. but,
This not only increases the number of parts, which is disadvantageous in terms of cost, but also increases the weight, which goes against the desired weight reduction of the vehicle body.

ものである。Therefore, the present invention improves the strength of the connection between the roof site rail and the rear biller without using a special reinforcing member.
The present invention provides an automobile body structure that can increase rigidity.

。According to the above embodiment structure, the roof side rail outer 3 and the rear pillar inner 6 are connected to the inclined wall 1 of the shape changing portion 11.
Since the roof sight rail 1 and the rear villa are integrally molded with the approximately hat-shaped cross section inverted at the boundary 2, the roof sight rail 1 and rear villa
At the junction with 2, the diagonal! 12 is interposed within the closed cross section to partition the closed cross section, allowing the inclined wall 12 to function as a reinforcement. In addition, since this slanted wall 12 is formed with a bead portion 13 that bulges toward the outside of the vehicle, the surface rigidity of the slanted wall 12 can of course be increased, and one side of the bead portion 13 is located on the roof side. Since the rail outer 3 and the rear pillar inner 6 are formed so as to straddle the area where the cross section changes in a substantially straight line and the bending rigidity is relatively weak, the shape changing part 11 can be reliably reinforced. The bending rigidity and torsional rigidity of the connection portion with the rear pillar 6 can be further increased. In addition, the overlapping portion between the rear end-membrane surface 4a of the roof side rail inner 4 and the front end-membrane surface 6a of the rear pillar inner 6 is such that the rear fender 5 is attached to the rear pillar inner 6° and the roof side rail outer 3 first. Although spot welding is not possible, the other side of the bead portion 13 is formed across the molded base of the oblique wall 12 on the rear pillar inner 6 side, and the overlapping area of the overlapping portion is reduced, so this non-spot welding portion There is no low-level noise caused by vehicle body vibration. Furthermore, the bead portion 13 of the inclined wall 12 has a side wall-film surface 13a.
The bead portion 13 of the roof side rail inner 4 is embossed so as to be parallel to the side wall-membrane surface 3a of the roof side rail outer 3, as shown in FIG.
When the mounting hole 14 is formed with a burr at a position corresponding to the mounting hole 14 and the tapping screw 15 is screwed into the part to fasten the rear end of the assist grip 16, a sufficient non-interference clearance for the tapping screw 15 can be secured. hand,
It is also possible to securely attach the assist grip 16.

ができる。In addition, the slanted wall has a bead portion to increase surface rigidity, and since this bead is formed across a portion where the roof side rail outer and the rear pillar inner change in cross section in a substantially straight line, the shape changes. Since the bending rigidity of the connecting portion is ensured, the strength and rigidity of the connecting portion can be further increased.
