To obtain a vehicle side part structure in which a linear expansion coefficient of a side member outer panel having an attachment part and a fragile part is larger than a linear expansion coefficient of an attached member and which can inhibit lifting of the side member outer panel and increase of the number of components.SOLUTION: A vehicle side part structure 30 has a front pillar lower reinforcement 32 and a side member outer panel 34. The front pillar lower reinforcement 32 has a linear expansion coefficient K1. The side member outer panel 34 has a hinge pillar part 52 formed with a fastening part 56 and a hole part 54 and has a linear expansion coefficient K2 larger than the linear expansion coefficient K1. The fastening part 56 is disposed in front of the hole part 54 in a vehicle fore and aft direction within a projection area S formed by projecting the hole part 54 in the hinge pillar part 52 in the vehicle fore and aft direction.SELECTED DRAWING: Figure 3

    【課題】取付部及び脆弱部を有するサイドメンバアウタパネルの線膨張係数が、被取付部材の線膨張係数よりも大きい車両側部構造において、サイドメンバアウタパネルの浮きを抑制すると共に部品点数の増加を抑制することができる車両側部構造を得る。【解決手段】車両側部構造30は、フロントピラーロアリインフォースメント32と、サイドメンバアウタパネル34とを有する。フロントピラーロアリインフォースメント32は、線膨張係数K1を有する。サイドメンバアウタパネル34は、締結部56及び孔部54が形成されたヒンジピラー部52を有し、線膨張係数K1よりも大きい線膨張係数K2を有する。締結部56は、ヒンジピラー部52における孔部54を車両前後方向に投影した投影領域S内で孔部54に対する車両前後方向の前側に配置されている。【選択図】図3
