PROBLEM TO BE SOLVED: To reduce deformation caused by thermal strain and improve dimensional accuracy while securing sufficient peeling strength.SOLUTION: In a skeleton component for an automobile, when as for a welded position coordinate is represented by such a coordination system that an end of a contact position between a flange portion and another frame component or a panel component is 0, a flange outer end side of the flange portion is represented by (-) and a vertical wall side in a substantial hat shape is represented by (+), a position X represented by relationship of -4t≤X≤-2t (t: plate thickness of frame component of substantial hat shape) is welded by one-sided welding.SELECTED DRAWING: Figure 1

    【課題】十分なはく離強度を確保しながら、熱歪による変形を低減させて寸法精度を向上させる。【解決手段】本発明に係る自動車用骨格部品は、溶接位置座標を、フランジ部と、他のフレーム部品またはパネル部品との接触位置の端部を0とし、フランジ部のフランジ外端側を(−)、略ハット形状における縦壁側を(+)とした座標系で表したときに、下記で表される位置Xが片側溶接にて溶接されているものである。−4t≦X≦−2t(t:略ハット形状のフレーム部品の板厚)【選択図】図1
