Abstract:
An object of the present invention is to provide a vibration damping device including a bearing member capable of achieving simplification of configuration in the vibration damping device, reducing frictional force during operation, and having an excellent wear resistance. A vibration damping device of the present invention includes a bearing structure, in which a metal bush (bearing member) has a resin layer on a side defined as a friction sliding surface of a base member, the resin layer includes polytetrafluoroethylene (PTFE) and a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer resin, and the metal bush is lubricated by a magneto-rheological fluid composition.

Claim (Index 3):
A vibration damping device comprising:\n a cylinder; a piston rod inserted into the cylinder; a piston connected to the piston rod and disposed axially slidably in the cylinder; a first liquid chamber and a second liquid chamber partitioned in the cylinder by the piston and filled with a magneto-rheological fluid composition; a communication hole formed in the piston so as to communicate the first liquid chamber and the second liquid chamber; and an electromagnetic coil for applying a magnetic field to the magneto-rheological fluid composition flowing through the communication hole, wherein the piston rod is slidably supported by the bearing member according to  claim 1  disposed in the cylinder.
