PROBLEM TO BE SOLVED: To provide an impact absorber reducing the load of the impact on a connecting member like a wire rope, and absorbing a larger amount of energy. SOLUTION: When a tensile force F is applied to the connecting member 14b in the state as shown in (1), a resisting body 12 moves in the direction of the tensile force F via the connecting member 14b. Consequently, an elastic body 11 is compressed by an end part 31 of the resisting body 12 and a reaction force is generated. Then, when the tensile force F exceeds a predetermined value, the end part 31 of the resisting body 12 is buried in a through-hole 21 of the elastic body 11 as shown in (2). In this occasion, the reaction force corresponding to the tensile force F is generated by the frictional force between the end part 31 of the resisting body 12 and the through-hole 21 of the elastic body 11, and is lowered below the reaction force generated by the axial directional compression of the elastic body 11 by the end part 31 of the resisting body 12. In this state, the resisting body 12 can be moved further in the direction of the tensile force F, and the amount of the energy absorption by the shock absorber 10a is increased.
