    • PROBLEM TO BE SOLVED: To provide superior damping effect from slight vibration such as traffic vibration to an earthquake by providing a load support part comprising alternately laminating a viscoelastic body and a reinforcing plate and an energy absorption part arranged in the hollow part of this load support part and constituting the energy absorption part from a column-shaped lead body and a viscoelastic layer. SOLUTION: A base isolation support device 1 comprises alternately laminating a viscoelastic body 5 and a reinforcing plate 6, a reinforcement mounting plate 7 having its hole for fitting dowel pin 4 is provided at both end parts of that laminating direction, and each of component members 5 to 7 is laminated and integrated by curing and adhering them. A hollow part 8 piercing through in the laminating direction is formed at the center part of the device 1, and a lead body 10 having a viscoelastic layer 9 around its body is densely sealed in this hollow part 8. Thereby, when great horizontal displacement acts on the base isolation support device 1, for example, by a large-scale earthquake, shear deformation is generated in the reinforcing plate 6 and the viscoelastic body 5, and earthquake energy is speedily absorbed by subsequent plastic deformation of the lead body 10.

    • PROBLEM TO BE SOLVED: To prevent the concentration of shearing forces into a fixing means like a bolt fixing the upper and lower fitting plates of a laminated rubber support body and the fitting member of the structure side and the foundation side. SOLUTION: Fitting members 10 comprising a disk part 11 and a cylindrical part 12 are arranged in the recesses 2, 5 of the upper and lower thick reinforcing plates 4, 7 of a laminated rubber support body 1. The disk part 11 is fitted in the reinforcing thick plate and the cylindrical part is protruded from the recessed opening. And in the cylindrical parts, the upper and lower fitting plates 13, 18 with pierced holes 14, 19 are arranged. The upper and lower thick reinforcing plates of the laminated rubber support body 1 and the upper and lower fitting plates are integrally fastened by bolts. The cylindrical parts of the fitting members protruded from the pierced holes 14, 19 of the upper and lower fitting plates are fitted into the fitting holes 25, 27 of the structural member side fitting member 26 and the foundation side fitting member 24 to arrange the laminated rubber support body 1 between both fitting members. And the upper and lower fitting plates are fixed to the structure side and the foundation side fitting members respectively.
