Abstract:
1. An elastic support unit for supporting a seismic isolation guide that is provided with mutually orthogonal track rails, said elastic support unit comprising two elastic supporters superposed in a vertical direction, each of the elastic supporters comprising: an elastically deformable bed plate; two mutually parallel side portions; and side wall portions extending between each of said two parallel side portions and said bed plate raising a lower surface of said bed plate a prescribed height above lower surfaces of said side portions and creating a space between said wall portions, wherein said two elastic supporters are arranged in a vertically opposite relation with respect to each other in such a manner that said bed plates are positioned at vertically opposite ends with said side wall portions being disposed orthogonal to each other, wherein one track rail of said seismic isolation guide is fixedly secured to the bed plate of one of said elastic supporters in parallel to the side wall portions thereof, wherein the bed plate of the other elastic supporter has a central portion supported by a load support part, and wherein vertical impacts are absorbed by the elastic deformations of the respective bed plates of said two elastic supporters.
