PROBLEM TO BE SOLVED: To provide an impact absorber capable of attaining the absorption of impact energy by plastic deformation by assuring the immersion of a small pipe body into a large pipe body even if an impact is applied from the axial slanting direction of a larger angle. SOLUTION: The small pipe body 101 and the large pipe body 106 are connected through a step-off portion 110 by partially contracting or expanding the diameter of a straight pipe capable of having plasticity work. The step-off portion 110 is a bumper support type impact absorber 105 formed by jointing a folded edge 107 of the small pipe body and a folded edge 108 of the large pipe body constituted of a circular-arc cross section of which the circular-arc angle is in excess of 90 degrees.
