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) 방향에 좌굴 변형하면서 흡수하는 축선(O) 방향으로 뻗은 중공 주상의 충격 흡수 부재(1)가, 복수의 벽부 중 적어도 2조의 인접하는 벽부에 의하여 형성되는 적어도 2개의 모서리부(1e, 1f, 1g, 1h)로부터 돌출하는 적어도 2개의 플랜지부(2a, 2b, 2c, 2d)를 구비하고, 이 적어도 2개의 플랜지부는 그 상기 모서리부로부터 돌출하는 방향이 둘레 방향에 있어서 동일한 방향을 향하도록 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), the shock absorbing member extending in the direction of axis (O) and absorbing externally-applied impact energy while buckling in the direction of axis (O). Shock absorbing member (1) is provided with at least two flanges (2a, 2b, 2c, 2d) protruding from at least two edges (1e, 1f, 1g, 1h) formed by at least two sets of neighboring walls among a plurality of walls, and the at least two flanges are arranged so that the directions of protrusion of the flanges from the edges are directed to the same direction with respect to a circumferential direction.
