  • Bearing member, and vibration damping device using same
    Patent number: 10634208
    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 and a tetrafluoroethylene-perfluoroalkyl vinyl ether copolymer resin, and the metal bush is lubricated by a magneto-rheological fluid composition.
    Type: Grant
