Seismic base isolation device
A seismic base isolation device (1) comprising an upper flange plate (2) coupled to an upper structure, a lower flange plate (3) coupled to a lower structure, and a laminated rubber body (7) having a rubber elastic material layer (4) and a rigid material layer (5) alternately layered in the vertical direction V, and that is provided between the upper flange plate (2) and the lower flange plate (3), wherein, of the rigid material layers (5), at least one of the upper rigid material layers (21, 22) disposed near the upper flange part (2) and/or at least one of lower rigid material layers (23, 24) disposed near the lower flange plate (3) is formed to be elongated in the horizontal direction with respect to intermediate rigid material layers (26, 27) of the plurality of intermediate rigid material layers (25, 26, 27) adjacent to the at least one rigid layer.
