Abstract

PURPOSE:To enable a vibration to be suppressed for a change of vibrating frequency by constituting a vibration suppressing structure fixedly providing electromagnets through brackets while floatably supporting a rigid unit by the electromagnets and changing a flow level of current in the electromagnet and a natural oscillation frequency of the rigid unit. CONSTITUTION:Electromagnets 7, 7 are arranged opposing their N and S poles in brackets 6, 6 fixedly provided in a vibration suppressing structure 1. In the intermediate between these electromagnets, a rigid unit 3 is movably fitted and supported floating by magnetic repulsive force of the electromagnets 7. Because the magnetic repulsive force by the electromagnet 7 changes by changing a level of electric current allowed to flow in the electromagnet 7, the natural oscillating frequency of the rigid unit 3 can be arbitrarily changed. Accordingly, even when the natural vibration frequency of the vibration suppressing structure 1 changes or even when an energized frequency from the outside changes, by changing the natural oscillating frequency of the rigid unit in accordance with these frequency changes, the vibration of the vibration suppressing structure 1 can be effectively suppressed.
