To provide a joining structure of a vehicle steel plate and a joining method for the vehicle steel plate capable of suppressing occurrence of breakage or the like due to impact or the like in the vicinity of a first welded portion in which a first steel plate and a second steel plate are welded.SOLUTION: In a vehicle to which a joining structure of vehicle steel plates is applied, a third welded portion 62 is set between: a first welded portion 56 at which a pillar outer rear side flange 44, an SM outer rear side flange 28, and a pillar inner rear side flange 54 are joined to one another; and a second welded portion 60 at which the pillar outer rear side flange 44 and the pillar inner rear side flange 54 are joined to each other. At the third welded portion 62, the pillar outer rear side flange 44 and the SM outer rear side flange 28 are joined to each other. Accordingly, tensile load F acting on the pillar outer rear side flange 44 is distributed toward the SM outer rear side flange side 28.SELECTED DRAWING: Figure 3
【課題】衝撃等による第1鋼板と第2鋼板とを溶接する第1溶接部の近傍における破断等の発生を抑制できる車両用鋼板の接合構造及び車両用鋼板の接合方法を得る。【解決手段】本車両用鋼板の接合構造が適用された車両では、ピラーアウタ後側フランジ44、SMアウタ後側フランジ28、ピラーインナ後側フランジ54が接合される第1溶接部56と、ピラーアウタ後側フランジ44とピラーインナ後側フランジ54とが接合される第2溶接部60との間に、第3溶接部62が設定される。第3溶接部62では、ピラーアウタ後側フランジ44とSMアウタ後側フランジ28とが接合される。このため、ピラーアウタ後側フランジ44に作用する引張荷重FがSMアウタ後側フランジ28側へ分散される。【選択図】図3
