Claims

[Scope of Claim for Utility Model Registration] A bush that allows two members to cooperate in relative vibration, comprising: an inner cylinder fixed to one member; an outer cylinder fixed to the other member; and the inner cylinder and the outer cylinder. an elastic body interposed between the cylinders; at least three liquid chambers formed in the elastic body at positions surrounding the inner cylinder; and a flow path communicating between the liquid chambers in the outer cylinder. an electrorheological fluid sealed in the liquid chamber and the flow path; and a plurality of electrodes that selectively apply a voltage to the electrorheological fluid in each flow path or a communicating portion between the flow path and the liquid chamber;
A vibration-proof bushing whose vibration transmission characteristics can be adjusted in each direction.
