Abstract: PROBLEM TO BE SOLVED: To obtain a compact spring element that has a damping characteristic as required. SOLUTION: The spring element made from the elastic material, in particular plastic (polyurethane), is composed of the pipe piece 1 and the bottom board 2 connected firmly therewith in order to absorb the kinetic energy. The pipe piece 1 has the wall thickness that is equivalent to smaller ratio than 2 of the outside diameter Da to the inside diameter Di and the total height He in the range of 0.7-1.3 times of the outside diameter Da. The turn of the face receiving the action of power is carried out at the open end of the pipe piece 1 in shrinking of approximately 35% of the total height.
