Abstract: An energy absorbing member (20) is formed of an aluminum alloy extruded material having a substantially quadrangular outer shape. Straight portions of a pair of long sides of a quadrangular shape are each segmented into three side walls (21a, 21b, 21c) by two arcuate internal projections (26) that project inward. Vertices of opposing internal projections (26) are joined by a rib (25). Accordingly, the energy absorbing member (20) is configured to have a shape in which three cylindrical portions having hollow portions (24a, 24b, 24c) are joined. Arc-shaped internal projections (23) that each project inward are provided in four corners of the quadrangular shape.

Abstract: A bumper structural body (100) includes a bumper reinforcement (10), energy absorbing members (30a, 30b), and intermediate members (50a, 50b). The sloped sections (12a, 12b) of the bumper reinforcement (10) are connected to the energy absorbing members (30a, 30b) and the intermediate members (50a, 50b). The intermediate members (50a, 50b) are each formed in a quadrilateral by connecting a first portion (51) contacting the energy absorbing member (30a, 30b), a second portion (52) contacting the bumper reinforcement (10), and portions connecting the first portion (51) and the second portion (52).
