  Further, the upper surface of the inner joint end portion 10 a of the side roof rail 10 excluding the contact portion between the outer contact portion 49 of the roof bow 40 and the inner joint end portion 10 a of the side roof rail 10 and the lower surface of the roof panel contact portion 22 of the roof panel 40. The side roof rail 10 and the roof panel 20 are joined by welding the inner joint end portion 10a and the roof panel contact portion 22 at the contact portion. That is, the side roof rail 10 and the roof panel 20 are welded and joined at a portion where the roof bow 40 is not interposed between the side roof rail 10 and the roof panel 20. Therefore, there are many target members to be welded (the side roof rail outer 11 of the side roof rail 10, the side roof rail inner 12, the reinforcement 13, the roof bow 40, and the roof panel 20). Thus, the roof panel 20 and the side roof rail 10 can be welded together efficiently.

  When the second step is adopted, the lower surface of the inner contact portion 48 of the roof bow 40 is brought into surface contact with the upper surface of the bottom surface portion 18a of the roof bow contact portion 18 so that the inner contact portion 48 and the roof bow contact portion 18 are brought into contact with each other. Are welded and joined by spot welding 63 at the surface contact portion, and the roof bow 40 and the side roof rail 10 are joined. Therefore, at the surface contact portion between the lower surface of the outer contact portion 49 and the upper surface of the inner joint end portion 10a. The roof bow 40 and the side roof rail 10 can be rigidly joined as compared with the case where the outer contact portion 49 and the inner joint end portion 10a are joined by welding.

  Further, since the front header contact portion 17 and the rear header contact portion 19 are provided, the assembly order can be selected for the front header 30 and the rear header 50 as well as the roof bow 40. One assembling order, the second assembling order, or the like can be appropriately employed.

  As mentioned above, although embodiment which applied the invention made | formed by this inventor was described, this invention is not limited with the description and drawing which make a part of indication of invention by this embodiment.

  For example, when the second assembling order is adopted, the front header contact portion 17, the roof bow contact portion 18 and the rear header contact portion 19 that are in surface contact with each other, the front inclined surface portion and the rear inclined surface portion, and the front header 30, the front inclined surface portion and the rear inclined surface portion of the bulging portions 31, 41, 51 of the roof bow 40 and the rear header 50 may be welded by spot welding.

  In this embodiment, the rail inner end portion 12a of the side roof rail inner 12 extends from the inner joint end portion 10a to form the roof bow contact portion 18, but instead, the rail outer end portion 11a or rain The force end portion 13a may be extended from the inner joint end portion 10a to form a roof bow contact portion. Further, the rail inner end 12a, the rail outer end 11a, and the reinforcement end 13a, or two of these, for example, the rail inner end 12a and the reinforcement end 13a, are connected to the inner joint end 10a. The contact portion for rule bow may be formed by extending from the contact portion.

  In the present embodiment, the inner contact portion 48 and the outer contact portion 49 are provided only on the roof bow 40, but the same inner contact portion and outer contact portion are provided on the front header 30 and the rear header 50. You may provide in a vehicle width direction both ends.

  That is, it should be added that other embodiments, examples, operation techniques, and the like made by those skilled in the art based on this embodiment are all included in the scope of the present invention.

  The present invention can be widely applied to a method of manufacturing a superstructure of a vehicle body having a roof panel reinforcing member.
