To provide a lap-welded joint structure and a suspension member which may suppress or prevent the generation of a gas defect such as a wormhole causing the mechanical characteristic reduction.SOLUTION: The lap-welded joint structure is a lap-welded joint structure including a fillet welding part which joins aluminum alloy base materials. The lap-welded joint structure includes one or more protrusions which are arranged on a mating surface of one aluminum alloy base material, projecting toward and contact a mating surface of the other aluminum alloy base material, and are continuous or discontinuous along an extension direction of the fillet welding part. The lap-welded joint structure has a gap that is formed of the one aluminum alloy base material, the other aluminum alloy base material and the fillet welding part and communicates in the extension direction of the fillet welding part.SELECTED DRAWING: Figure 2

    【課題】機械的特性低下の要因となるワームホールのようなガス欠陥の発生を抑制ないし防止し得る重ね溶接継手構造及びサスペンションメンバーを提供する。【解決手段】重ね溶接継手構造は、アルミニウム合金母材同士を接合するすみ肉溶接部を備えた重ね溶接継手構造である。重ね溶接継手構造は、一方のアルミニウム合金母材の合わせ面に、他方のアルミニウム合金母材の合わせ面に向かって突出して当接し、すみ肉溶接部の延在方向に沿って連続又は断続した凸部を有する。重ね溶接継手構造は、一方のアルミニウム合金母材と他方のアルミニウム合金母材とすみ肉溶接部とで形成され、すみ肉溶接部の延在方向に連通した隙間を有する。【選択図】図2
