振を避ける。 Next, how to use it will be explained. As mentioned above, the device of the present invention is used as the foundation of an outdoor building, and the rubber body 1 contributes to vertical vibrations such as traffic vibrations. The function is the same as that of conventional anti-vibration rubber, and the natural frequency of the building is changed by the spring constant of the rubber body 1 to avoid resonance with the vertical vibration of the ground.

ない場合、点線が本発明装置の場合である。 On the other hand, in the event of an earthquake, the controller 4 weakens the magnetic force of the electromagnet 3 to reduce the rigidity of the device. In this way, the rubber body 1 deforms as shown in Fig. 2 in response to horizontal vibration caused by an earthquake, and the electromagnets 3 try to separate from each other, but the displacement is attenuated by the restoring force of the magnetic force. . FIG. 3 shows this situation, where the solid line shows the case where there is no magnetic force due to the electromagnet 3, and the dotted line shows the case with the device of the present invention.
