Abstract

PURPOSE:To enable a vibration damping device to simply deal with various vibration characteristics, by partitioning a small liquid chamber and an air chamber from each other with the use of an elastic film, and by disposing a vibration damping container in a vibration damping liquid chamber which is therefore communicated with the small liquid chamber through a restricting passage. CONSTITUTION:A vibration damping container 26 is movably disposed in a vibration damping liquid chamber 24. Further, a vibration damping device body 10 is secured to a vehicle body with the use of a bolt 14, and an engine is mounted on a top plate 20 with the use of a bolt 22. With this arrangement vibration from the engine is transmitted to a rubber 18 through the top plate 20, and therefore, vibration is absorbed due to the internal friction of the rubber 18. Further, upon vibration liquid flows between a vibration damping liquid chamber 24 and a small liquid chamber 36 through an orifice 38 so that vibration is absorbed due to resistance upon passage of the liquid through the orifice 38. Further, the vibration damping liquid chamber 24 is formed in accordance with a desired vibration damping characteristic so that the vibration damping device body 10 may be formed in a uniform shape while the device may cope with various required characteristics.
