PROBLEM TO BE SOLVED: To suppress deformation due to local expansion by welding heat at a jointing part of a structure body including a dissimilar material jointing structure.SOLUTION: A vehicle body 10 including a dissimilar material jointing structure comprises a roof panel 200 and a skeleton body 100. The roof panel 200 is an aluminum-alloy-made panel member having a bending part 201 at the end part. The skeleton body 100 is steel made and has a support part 154 for supporting the roof panel 200. The roof panel 200 and the skeleton body 100 are jointed to each other by welding continuously the apex 202 vicinity of the bending part 201 of the roof panel 200 and the support part 154 of the skeleton body 100, and a reinforcement plate 210 is jointed to the roof panel 200 at least partially along the jointing part with the skeleton body 100.SELECTED DRAWING: Figure 7

    【課題】異種材料の接合構造を含む構造体の接合部において、溶接熱による局部的な膨張による変形を抑制する。【解決手段】異種材料の接合構造を含む車体10は、ルーフパネル200と骨格ボデー100とを備える。ルーフパネル200は、端部に折曲部201を有するアルミニウム合金製のパネル部材である。骨格ボデー100は、ルーフパネル200を支持するための支持部154を有する鋼製である。ルーフパネル200及び骨格ボデー100はルーフパネル200の折曲部201の頂点202付近と骨格ボデー100の支持部154とを連続溶接することによって接合され、ルーフパネル200は骨格ボデー100との接合部に沿って少なくとも部分的に補強板210が接合されている。【選択図】図7
