To provide a connection structure of members having a connection structure of high versatility allowing optional setting of member strength of a connection part, and capable of preventing fatal damage of a structure by forcibly breaking the connection part in case of excessive loading case like a large earthquake.SOLUTION: A connecting fitting 3 and a connecting fitting 4 are attached to each of connection ends of a structural member 1 and a structural member 2. Multiple bearing plates 3a, 3b separating in the continued direction of the structural member 1 and the structural member 2 are provided to the connecting fitting 3 and the connecting fitting 4. The multiple bearing plates 3a, 3b of the connection fitting 3 and the multiple bearing plates 4a, 4b of the connecting fitting 4 are arranged in a staggered state in the connection direction, with projection planes of the structural member 1 and the structural member 2 in the continued direction overlapped, and the connecting fitting 3 and the connecting fitting 4 are fixed with each other with connection bolts 5.SELECTED DRAWING: Figure 1 【課題】連結部の部材強度を任意に設定できる汎用性の高い連結構造で、かつ大地震時など過大荷重時には、連結部を強制破断させ構造体の致命的な損壊を未然に防止できる部材間の連結構造を提供する。【解決手段】連結される構造部材１と構造部材２のそれぞれの連結端部に連結金具３と連結金具４を取り付ける。連結金具３と連結金具４に、それぞれ構造部材１と構造部材２の連続する方向に離間する複数の支圧板３ａ,３ｂを設ける。連結金具３の複数の支圧板３ａ,３ｂと連結金具４の複数の支圧板４ａ,４ｂが連結方向に互い違いとなるように、かつ構造部材１および構造部材２の連続する方向の投影面が重なり合うように配置された状態で、連結金具３と連結金具４同士を連結ボルト５で固定する。【選択図】図１
