PURPOSE:To obtain a shock absorber disposable without problems, excellent in protecting function, effective in utilization of resources and excellent in economical property, by combining a recessed rigid member having a tapered slant of the inside face with a protruding elastic member provided with a protrusion having a sliding face parallel to this inside face. CONSTITUTION:A shock absorber 10 is constituted by the combination of a protruding elastic material 20 made of rubber and a recessed rigid member 30 made of hard synthetic resin. A trapezoidal grooved recession 22 is formed at the recessed rigid member 30 and the inside faces 34 on both sides of the recession 32 is slanting as a taper. The protruding elastic member 20 has a little smaller trapezoidal section than the recession 32 of recessed rigid member 30 and the side faces 22 thereof have tapered slants and the slope of the sides 22 is the same as the inner face 34 of the recessed rigid member 30. And a protrusion 24 projecting outward and crossing in right angles with the side face 22 is provided in the middle of the side face 22. And a flat sliding face 26 parallel to the inner side face 34 of the recessed rigid member 30 is formed at the top face of the protrusion 24. |
