<p>PROBLEM TO BE SOLVED: To provide an impact absorption structure capable of holding an energy absorption member without blockage of the evolution of progressive crushing while increasing the degree of freedom of the arrangement of a fastening hole, into which a bolt is inserted for coupling the energy absorption member, and a through-hole.SOLUTION: An impact absorption structure 9 formed of a tubular type composite material having a plurality of layers in a radial direction, comprises: an energy absorption member 5 absorbing the impact energy applied to a protection target; a pressing part 12 that is provided apart from the protection target, and to which one end of the energy absorption member is disposed opposite; a support part 13 that is provided in the protection target, and to which the other end of the energy absorption member is disposed opposite; and a bolt 10 provided in the energy absorption member for coupling the energy absorption member to the support part by inserting the bolt 10 into a through hole 8c provided in the energy absorption member. When the pressing part 12 is pressed by an impact, the bolt has the strength to break before an inner wall is damaged, the inner wall forming the fastening hole or the through hole of the energy absorption member.</p> |
