축선(O)과, 상기 축선(O)에 대하여 평행하게 뻗은 복수의 직사각형의 벽부(1a, 1b, 1c, 1d)와, 축선(O)에 대하여 수직인 다각형 단면을 가지고, 외부로부터 가하여지는 충격 에너지를 축선(O) 방향으로 좌굴 변형하면서 흡수하는, 축선(O) 방향으로 뻗은 중공 주상의 충격 흡수 부재(1)에 있어서, 복수의 벽부(1a, 1b, 1c, 1d) 중에서 적어도 1개의 벽부(1a, 1b, 1c, 1d) 에 형성된 좌굴 변형의 단서를 제공하는 적어도 1개의 비드부(2a, 2b, 2c, 2d)를 구비하고, 이 적어도 1개의 비드부(2a, 2b, 2c, 2d)는 이 비드부(2a, 2b, 2c, 2d)가 형성되어 있는 벽부(1a, 1b, 1c, 1d)의 축선(O)에 평행하게 뻗은 한쪽의 가장자리부에 치우치게 하여 배치되어 있다.

    A hollow columnar shock absorbing member (1) has an axis (O), a plurality of rectangular walls (1a, 1b, 1c, 1d) extending parallel to axis (O), and a polygonal cross-section perpendicular to axis (O), wherein the shock absorbing member extends in the direction of axis (O) and absorbs externally-applied impact energy while buckling in the direction of axis (O). The shock absorbing member has at least one bead (2a, 2b, 2c, 2d) formed on at least one wall (1a, 1b, 1c, 1d) among the plurality of walls (1a, 1b, 1c, 1d), the at least one bead (2a, 2b, 2c, 2d) providing the origin of the buckling. The at least one bead (2a, 2b, 2c, 2d) is positioned so as to be deviated towards one edge of a wall (1a, 1b, 1c, 1d) on which the at least one bead (2a, 2b, 2c, 2d) is formed, the edge extending parallel to axis (O).
