ようにされたことを特徴とする免震ゴム。 In a seismic isolation rubber formed by alternately arranging a plurality of rubber layers and metal plates, the spring constant of each of the plurality of rubber layers in the horizontal direction is approximately constant, and each thickness and each of the plurality of rubber layers are substantially constant. A seismic isolation rubber characterized in that Young's modulus is made to increase sequentially from the middle rubber layer to the rubber layers at both ends.
