され、免振ダンパ１は有効に作用する。 Since the seismic isolation damper 1 has the above configuration, in normal times, the seismic isolation damper 1 has four oil dampers 6 connecting the respective pedestals 3a and 5a, as shown in FIG. It is pivotally supported in two horizontal directions that are perpendicular to each other. However, in the event of an earthquake, the relative positional relationship between the pedestal 3a on the foundation 3 side and the pedestal 5a on the supported body 5 side changes, and the distance between the pedestals 3a and 5a to which each oil damper 6 is connected also changes. do. Then, each oil damper 6 is connected to the rod 6b.
The earthquake energy is effectively absorbed by attenuating and absorbing the vibrations. The oil damper 6, the supported body 5, and the foundation 3 are mutually pivotally supported in a circular shape with a rectangular planar shape. It is damped in a shared manner by the damper 6, and vibrations in a direction different from the damping direction that are harmful to the operation of the oil damper 6 are prevented from acting on the oil damper 6, and the vibration isolation damper 1 acts effectively. .

可能となる。(g) Effect of the Invention As explained above, according to the present invention, the structure is installed between the foundation 3 of the building 2 and the supported body 5 supported by the foundation to absorb seismic energy during an earthquake. In the seismic isolation damper 1, a viscous damper 6 such as an oil damper 6 is installed between the foundation and the supported body.
, one end of the viscous damper is placed on the base 3a,
It is connected via a first pivot support means such as a bolt 3b, and the other end is connected to the supported body by a pedestal 5a and a bolt 5.
A viscous damper connected via a second pivot support means such as b and provided between the first and second pivot support means is connected to the first and second pivot support means at the apex. Since the viscous dampers form each side and are connected to each other in a ring shape so that the planar shape forms a polygonal shape such as a quadrangle, seismic energy is effectively absorbed by each viscous damper. . In addition, since the structure is simple in that the viscous dampers are connected annularly to each other in a polygonal planar shape, it is possible to provide the seismic isolation damper 1 with less possibility of failure.
