To provide a closed cross-sectional structure that can suppress peeling of a flange connection surface even in a case where compressive force or bending deformation is applied in an axial direction, without making a flange into a special shape so as to facilitate press molding, spot welding and connection with another member.SOLUTION: A closed cross-sectional structure is configured such that a first hat-shaped member having a first flange and a second hat-shaped member having a second flange are joined via the first flange and the second flange, wherein a maximum flat surface width of the closed cross-sectional structure is larger than an effective width calculated from Karman's effective width formula.SELECTED DRAWING: Figure 1
【課題】プレス成形、スポット溶接、及び他の部材との接合を容易に行うことができるようにフランジを特殊な形状にすることなく、軸方向に圧縮力や曲げ変形が加えられてもフランジ接合面の剥離を抑制することができる閉断面構造体を提供する。【解決手段】第1のフランジを有する第1のハット形部材と第2のフランジを有する第2のハット形部材とが、前記第1のフランジ及び第2のフランジを介して接合された閉断面構造体であって、カルマンの有効幅式から計算される有効幅よりも、前記閉断面構造体の最大平坦面幅が大きい閉断面構造体。【選択図】図1
