<P>PROBLEM TO BE SOLVED: To provide a structural member excellent in collapse characteristics where a front board is hard to buckle and has a high collapse load. <P>SOLUTION: The impact absorbing member 10 is constituted such that a hollow structure is formed with both an approximately semicircle like front face plate 12 and a straight line like back board 14 connecting both ends of the front face plate 12, and a central axis Z of the cross section of the impact absorbing member 10 is placed between the front face plate 12 and the back board 14, which passes through a point O of the center of a width direction of the back board 14 intersects perpendicularly to the back board 14, with two connection boards 16 and 16 tilting to the central axis Z whose inclination direction are mutually opposite are arranged to become a line symmetry to the central axis Z, and finally the front face plate 12 and the back board 14 are connected in one with the two connection boards 16 and 16. <P>COPYRIGHT: (C)2013,JPO&INPIT |
