To obtain a vibration control device synthetically improving vibration suppressing performance though providing basically an active type to be capable of sufficiently suppressing even fine vibration and low frequency vibration further with a point of advantage provided of a passive type.
This device, provided with a basement 2 elastically supported to a fixed part 19 through an air spring 1, total six of upper/lower front/rear right/left electromagnets 7 to 12 supporting a mass body 3 in a levitation condition relatively movably to the basement also forcedly moving the mass body 3, and a vibration sensor 6 detecting vibration of the basement 2 relating to the fixed part 19 to output a vibration signal, operates the electromagnets 7 to 12 based on an output signal of the vibration sensor 6, and a controller 5 linking the vibration sensor 6 and the electromagnets 7 to 12, so as to move the mass body 3 relating to the basement 2 in a direction suppressing its vibration, is provided.
