<p>A hollow, columnar shock absorbing member (1) having an axis line (O), a plurality of rectangular walls (1a, 1b, 1c, 1d) extending parallel to the axis line, and a polygonal cross-section perpendicular to the axis line (O), said shock absorbing member (1) extending in the direction of the axis line (O) and absorbing externally-applied impact energy while buckling in the direction of the axis line (O). The 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 adjacent walls from the plurality of walls, and these flanges are arranged so that the direction of protrusion from the edges faces the same direction in the circumferential direction.</p> |
