To provide a stacked-joint structure capable of suppressing breakage of a plate member starting from a hole formed in a non-fused joint of the plate member, thereby increasing the elongation (strain amount) until the plate member breaks.SOLUTION: A stacked-joint structure according to one aspect of the present invention includes: a plurality of stacked plate members; and a plurality of joints arranged in a stacked portion of the plurality of stacked members, the joints being formed by mechanical joining means or friction-agitation point joining means. The plurality of joints have holes through which the mechanical joining means is inserted or holes formed by the friction-agitation point joining. One or more of the plurality of plate members have hard portions around the holes.SELECTED DRAWING: Figure 1
【課題】板部材の非溶融接合部に形成される穴を起点とした板部材の破断を抑制し、これにより板部材が破断するまでの伸び(歪量)を大きくすることが可能な重ね接合構造を提供する。【解決手段】本発明の一態様に係る重ね接合構造は、重ね合わせられた複数の板部材と、前記複数の板部材の重ね部に設けられた、機械的接合手段又は摩擦撹拌点接合手段によって構成された複数の接合部と、を備え、前記複数の接合部は、前記機械的接合手段が挿通される穴、又は摩擦撹拌点接合によって形成された穴を有し、前記複数の板部材のうち1枚以上において、前記穴の周囲に硬質部が設けられている。【選択図】図1
