To provide a shock absorber to exert a restoration force both in a compression direction and a tension direction and increase a damping force, and perform movement in a vertical direction, a horizontal direction, and an oblique direction, and absorb a shock due to displacement and avoid a rapid load.
Structure is formed such that universal joints 7 and 8 are arranged at the upper and lower ends of a buffering metal fitting 2 and support plates 9 and 10 to support a load are mounted on the tips of the respective universal joints 7 and 8, and a mechanism is such that a rubber body 5 is properly compressed by a pair of U-shaped metal fittings 3 and 4. Further, A contact part 6 is arranged in a manner to protrude downward from the compression plate 19 of the U-shaped metal fitting 3 slid over the lower two ends of the U-shaped metal fitting 3. A pair of U-shaped metal fittings 3 and 4 making contact with the internal part of the U-shaped metal fitting 4 are supported. In this case. The U-shaped metal fitting 3, the compression plate 19, and the contact part 6 are integrally manufactured. Further, the inner side of a buffering container 2 is coated with silicone oil but wear resistance resin may be applied or a resin plate and a metallic plate may be arranged.
