PROBLEM TO BE SOLVED: To provide a laminated rubber bearing capable of keeping seismic isolation performance from declining due to torsional deformation.SOLUTION: A laminated rubber bearing 1 has a laminated rubber 101 layering a plurality of rubber layers 104a and a plurality of steel plates 105 and supports a superstructure 3 by being placed between the same and a substructure 2. The laminated rubber 101 also has a reinforcing layer (rubber layer 104b) made of a rubber material with a lower attenuation constant than the rubber layer 104a. |
