To produce an inexpensive shock-absorbing member from a material of a steel plate with high productivity.SOLUTION: A method includes: a closed cross section-forming half part formation step S1 in which each closed cross section-forming half part is formed by press-molding a steel plate blank into a hat-shaped cross section having a hat section and a pair of brim sections; and a closed cross section-forming body formation step S2 in which at least two closed cross section-forming half parts are combined in a posture in which convex directions of the respective hat sections are opposite to each other, and a top of the hat section of one closed cross section-forming half part and the brim sections of the other closed cross section-forming half part are stacked and joined to form a closed cross section-forming body.SELECTED DRAWING: Figure 7
【課題】鋼板を材料とする安価な衝撃吸収部材を生産性よく製造する。【解決手段】鋼板のブランクを帽子部と一対のつば部を有する断面ハット状にプレス成形して閉断面構成半部を形成する閉断面構成半部形成ステップS1を有する。少なくとも二つの閉断面構成半部を帽子部の凸になる方向が互いに反対になる姿勢として組み合わせ、一方の閉断面構成半部の帽子部の頂部と他方の閉断面構成半部のつば部とを重ねて接合し、閉断面構成体を形成する閉断面構成体形成ステップS2とを有する。【選択図】 図7
