(1)項記載の流体封入式防振支持装置。[Scope of Claim for Utility Model Registration] (1) A fluid chamber surrounded by a rubber peripheral wall and filled with electrorheological fluid, and a rigid body provided to divide this fluid chamber into a main chamber and a sub-chamber, both of which have openings. A fluid-filled type barrier that changes the viscosity of an electrorheological fluid flowing between a main chamber and a sub-chamber through openings in the two electrode plates by applying a voltage to the electrode plates. In the vibration support device, a first opening is formed in the center of one electrode plate, and a plurality of second openings are formed along the outer peripheral edge of the other electrode plate. Shaking support device. (2) Claims for registration of a utility model characterized in that the second opening is formed on the outer peripheral edge of the other electrode plate on the same circumference that is concentric with the first opening.
The fluid-filled vibration damping support device described in (1).
