PROBLEM TO BE SOLVED: To provide a base isolation device capable of displaying a sufficient base isolation effect regardless of its simple constitution because base isolation structuring of a low building of a general housing, etc., is desired as a large earthquake recently occurs in various areas of the world though development of a base isolation device which can be corresponded to a small scale building such as a housing, etc., is conventionally small. SOLUTION: This base isolation device is a device sealing an object made by laminating alternately laminating rubber 4 and sliding support parts in a support outer part by forming the support outer part by providing collar parts on upper and lower end parts of a cylindrical rubber body, forming an upper part disc 5 and a lower part disc 6 by assembling fronts and backs of a plural number of plates different in material quality, providing hollow parts in central inner parts by laminating these upper and lower discs 5, 6 and forming the laminated rubber 4 by laminating a plural number of annular rubber plates and cover bodies 12 are installed on upper and lower collar parts 11 of the support outer part. |
