ABSTRACT:
A resin shock absorber comprising a compression deformable portion made of a resin having a flexural modulus of elasticity of 500 to 20,000 kg/cm.sup.2, said shock absorber having a yield strength of 2 to 25 kN/m.sup.2 and a compressive energy absorption efficiency of 50% or higher. The shock absorber of the present invention has a high energy absorption efficiency for its reaction force, superior restorability, and is maintenance-free since the absorber has resistance against corrosion, water and weather. Therefore, the absorber is applicable to the use in the sea, on the ground, as well as above the ground. Furthermore, the shock absorber can be easily extended on demand into a block shock absorber, which is light in weight and simple in structure and capable of exhibiting uniform cushion characteristics over an extended area.
