Description of the Related Art Conventionally, for example, machines and equipment such as computers and precision machines are arranged indoors and indoors, and various cultural heritage, A large number of mounting tables and mounting cases are installed, each of which carries various kinds of mounted objects such as valuable Buddha statues, fine arts such as sculptures, and valuable paintings. Conventionally, these mounting tables,
Since the mounting case is installed directly on the floor indoors and indoors, when vibration such as an earthquake occurs, the mounting table and the mounting case collapse and the mounted items such as computers and artworks are damaged or damaged. And irreparable damage will be incurred. In order to avoid such damages in advance, conventionally, a mounting table for storing a load and a mounting case have a strong structure. However, in this case, the cost is high, and in the case of such a structure, the mounting table and the mounting case are collapsed against a vibration such as a large earthquake. Therefore,
Conventionally, in order to avoid the above-mentioned inconveniences, an elastic body such as an oil damper or rubber is placed between the installation surface and the mounting table and the mounting case under the mounting table so that the vibration can be absorbed by the shear deformation. There are configured seismic isolation devices. Also,
Under the mounting base, a plurality of bases with rollers interposed are arranged, and the structure is such that multiple bases move back and forth, left and right in response to an earthquake, so that the movement of each base can absorb vibration. There is a configured seismic isolation device.

とができる免震装置を提供することにある。However, an elastic body such as an oil damper or rubber is disposed between the installation surface, the mounting table, and the mounting case under the above-mentioned conventional mounting table, and vibration is generated by the shear deformation. In a seismic isolation device or the like configured to be able to absorb the vibration, it is often difficult to absorb the vibration generated by a large earthquake or the like using only such an elastic body. In addition, in the case of a seismic isolation device having a structure in which a plurality of mounts with rollers interposed therebetween are arranged under the above-described conventional mount, and the plurality of mounts move back and forth in response to an earthquake, left and right, Since each platform simply moves back and forth, left and right, the range in which each moving platform can be moved without falling off and out of each other is a limited narrow range. The place where this seismic isolation device is installed will require a fairly large space,
There is an inconvenience that it is impossible to apply this seismic isolation device to very existing or ready-made mounting tables, mounting cases, and the like.
The present invention has been developed in view of the above-described conventional circumstances, and has an object of absorbing floor vibration by absorbing horizontal vibration even in the case of occurrence of various types of earthquakes, large or small. Computer on a table, placed on a surface
Prevents situations such as the fall of machinery and equipment such as precision machinery, various types of mounted items on the mounting table, and various mounted items stored in the mounting case, etc., and the mounting table after the occurrence of vibration such as an earthquake. It is an object of the present invention to provide a seismic isolation device that can smoothly and quickly return to the original position, and can be installed in a relatively small space, and can be directly applied to existing and ready-made mounting tables, mounting cases, and the like. .

This makes it possible to further quickly return the movable gantry of the lower gantry 10 and the intermediate gantry 20 to their original positions. In addition, the support position of the holding frame 93 on the nut 96 of the stopper body 90 can be freely and easily adjusted by the tightening state of the nut 91, so that the roller 71 on the stopper receiving surface 53 can be adjusted. Can be adjusted, so that the horizontal movement of the lower frame 10 and the intermediate frame 20 can be freely adjusted in the front-rear, left-right, and right-and-left directions, respectively.
