Abstract

PURPOSE:To optionally change the spring constant of a damper and more finely control its absorption of vibration, by such constitution that a magnetic fluid is sealed in the damper part simultaneously a flow of this fluid is electrically controlled. CONSTITUTION:In case of constitution as an engine mount 2, a rubber member 7 is deformed by vibration in a state when an electromagnet 8 is not electrically conducted, then a magnetic fluid in chambers 4, 14 moves through a small hole 6, located in a gap part 13 in both end parts of an iron core 9, by deforming a rubber plate 5. At this time, the small hole 6 being fixed in its size can not finely control absorption of vibration. On the contrary, if the electromagnet 8 is electrically conducted, magnetic flux is concentrated to a part of the small hole 6, and a virtual viscosity value of the magnetic fluid in this small hole part 6 is changed in accordance with a level of electric current. Accordingly, circulative resistance of the small hole 6 can be optionally changed to more finely control absorption of vibration.
