To inhibit increase of an initial load acting on a second member preferably.SOLUTION: An impact absorption member 10 includes a first cylindrical body 20 and a second cylindrical body 40 respectively having axis lines L1, L2 extending along a direction in which a first member 91 and a second member 92 face each other. The first cylindrical body 20 has: a cylindrical first side wall 22; and a polygonal first bottom wall 21 which closes an end on the first member 91 side of the first side wall 22. A second member 92 side end of the first side wall 22 is open. The second cylindrical body 40 has: a cylindrical second side wall 42; and a polygonal second bottom wall 41 which closes an end on the second member 92 side of the second side wall 42. An end on the first member 91 side of the second side wall 42 is open. The first cylindrical body 20 and the second cylindrical body 40 are disposed adjacent to each other. The first side wall 22 and the second side wall 42 are connected with each other in a part in a circumferential direction of the side walls.SELECTED DRAWING: Figure 1

    【課題】第2部材に作用する初期荷重の増大を好適に抑制することができる。【解決手段】衝撃吸収部材10は、第1部材91と第2部材92との対向方向に沿って延びる軸線L1,L2をそれぞれ有する第1筒体20及び第2筒体40を備える。第1筒体20は、筒状の第1側壁22と、第1側壁22の第1部材91の側の端を閉塞する多角形状の第1底壁21とを有し、第1側壁22の第2部材92の側の端が開放されている。第2筒体40は、筒状の第2側壁42と、第2側壁42の第2部材92の側の端を閉塞する多角形状の第2底壁41とを有し、第2側壁42の第1部材91の側の端が開放されている。第1筒体20と第2筒体40とは、互いに隣り合って配置されている。第1側壁22と第2側壁42とは、各々の周方向の一部において互いに連結されている。【選択図】図1
