Further, the front upper flange 64 and the front inner flange 55 are spot-welded at the second spot weld portion 93. Therefore, the second spot welded portion 93 is positioned in the vicinity of the roof-side spot welded portion 92, so that the front inner flange 55 (inner extension portion 37) is made to continue in a substantially horizontal direction with respect to the front lower flange 74 (arch lower 72). It can be kept in the state. Thereby, as shown in FIG. 14, the connection part 19 of the rail member 15 and the arch member 18 can be maintained at a closed cross section. Thus, the rigidity of the connecting portion 19 can be sufficiently secured by keeping the connecting portion 19 of the rail member 15 and the arch member 18 in a closed cross section.

- the upper projecting portion 65 and the outer projecting portion 47 are spot welded so that the front upper flange 64 and the front outer flange 46 are firmly coupled. Since the front upper flange 64 and the front outer flange 46 are firmly coupled, the arch upper 62 and the outer extension portion 33 are firmly coupled.
- the rail member 15 and the arch member 18 are suitably coupled by firmly coupling the arch lower 72 and the inner extension portion 37 and firmly coupling the arch upper 62 and the outer extension portion 33.
- the roof-side spot welded portion 92 and the second and third spot welded portions 93 and 94 are provided at a predetermined distance from the first spot welded portion 91 on the center side in the vehicle width direction. In this way, by separating the welded portions 92 to 94 from the first spot welded portion 91 toward the center in the vehicle body width direction, the stress acting on the connecting portion 19 of the rail member 15 and the arch member 18 can be reduced.
- the first spot welds 91 can be suitably dispersed. Thereby, the rigidity of the connection part 19 of the rail member 15 and the arch member 18 is fully securable.
- the upper spot 65 and the outer projection 47 are coupled to each other by the first spot weld 91, and the arch upper 62 and the outer extension 33 are coupled to each other at the first spot weld 91. Is done. Further, the front lower flange 74 (the end 74a on the outer side in the vehicle width direction) and the front inner flange 55 (the end 55a on the center side in the vehicle width direction) are joined by the welds 92 to 94, so 72 and the inner extension 37 are coupled.
- the first spot welded portion 91 of the arch upper 62 and the outer extension portion 33 and the welded portions 92 to 94 of the arch lower 72 and the inner extension portion 37 can be separated from each other.
- the stress acting on the connecting portion 19 of the rail member 15 and the arch member 18 can be suitably dispersed in the welded portions 92 to 94 and the first spot welded portion 91. Therefore, the rigidity of the connecting portion 19 of the rail member 15 and the arch member 18 can be sufficiently ensured.
- a side-side welded portion 96 is provided on the outer side in the vehicle width direction from the fourth spot welded portion 95 and on the center side in the vehicle width direction from the rail inner 36 (FIG. 6).
- the side-side welded portion 96 is a portion where the front roof flange 22, the side flange 16 a of the side panel 16, and the joint portion 55 d (that is, three pieces) of the front inner flange 55 are spot-welded.

- the rail member 15 and the arch member 18 are provided so as to be substantially orthogonal. For this reason, when the rail member 15 and the arch member 18 are connected by the intersection part 26 (FIG. 4), stress concentrates on the intersection part 26 and it is difficult to ensure the rigidity of the intersection part 26.
- the rail outer 32 is integrally provided with the outer extension portion 33
- the rail inner 36 is integrally provided with the inner extension portion 37.
- the arch upper 62 is provided in the outer extension 33 and the arch lower 72 is provided in the inner extension 37. Therefore, since the connection part 19 of the rail member 15 and the arch member 18 can be separated from the crossing part 26, the rigidity of the crossing part 26 can be improved. Thereby, for example, the load F (FIG. 4) applied from the front of the vehicle body can be suitably transmitted to the arch member 18 via the rail member 15 and the intersection 26.
- the vehicle body side part structure 10 is provided with a roof panel 20 above the arch member 18, so that the arch member 18 is covered with the roof panel 20.
