Abstract

PURPOSE: To shut off the transmission of vibrations applied from the outside by disposing electromagnets on a borne part so that they correspond to permanent magnets disposed on a foundation, and bearing the borne part in a condition of floating up from the foundation, the electromagnets having different polarities from those of the permanent magnets. CONSTITUTION: Permanent magnets 6 are disposed on a foundation 5 and electromagnets 7 with opposing different polarities from those of the permanent magnets 6 are disposed on a borne part such as a building 4 so as to correspond to the permanent magnets 6. The borne part held floated by means of the repulsion of magnetic force is borne on the foundation 5. Transmission of vibrations applied from the outside can thus be shut off.
