To provide an impact absorbing material that improves impact absorption performance and is easy to deform from one end side in comparison to conventional impact absorbing materials.SOLUTION: A shock absorbing material (2) has a cylindrical body part (2c) whose cross-sectional area increases from one end side to the other end side. In a cross section of the body part (2c) perpendicular to an axis from the one end side to the other end side, for an ellipse (12) inscribed in a rectangle (rectangular cross section) (11), the shock absorbing material (2) has a cross-sectional shape connecting points (c1 to c5) set between the edge of the ellipse (12) and the edge of the rectangle (rectangular cross section) (11) along a plurality of virtual line segments (14a to 14e) that extends toward the edge of the rectangle (rectangular cross section) (11) at predetermined phase intervals with the center of the rectangle (rectangular cross section) (11) as a center (11a).SELECTED DRAWING: Figure 3

    【課題】従来の衝撃吸収材に比べて、衝撃吸収性能を向上させつつ、一端側から変形しやすい衝撃吸収材を提供すること。【解決手段】一端側から他端側に行くにつれて断面積が大きくなる筒状の本体部(2c)を有する衝撃吸収材(2)であって、一端側から他端側に向かう軸線に対して垂直な本体部(2c)の断面において、矩形(矩形断面)(11)に内接する楕円(12)に対し、矩形(矩形断面)(11)の中央を中心(11a)として予め定められた位相の間隔で矩形(矩形断面)(11)の縁に向けて延びる複数の仮想線分(14a〜14e)に沿って、楕円(12)の縁と矩形(矩形断面)(11)の縁との間に設定された点(c1〜c5)どうしを結ぶ断面形状を有する衝撃吸収材(2)。【選択図】図3
