PURPOSE:To decrease a moving amount of fluid so as to set a loss coefficient nearly to an ideal value and obtain suitable damping force, by both combining a mounting member with a base member by an elastic member and additionally providing a diaphragm in the base member so as to form a fluid chamber while connecting a side of the mounting member to a side of the base member by a new elastic member, with moving capability of fluid different from afore said elastic member, so as to form said fluid chamber into two chambers. CONSTITUTION:A mounting member 10 connected to a vibrative source is combined with a base member 20 by an elastic member 30 of relatively large area consisting of rubber material while a diaphragm 40 is additionally provided in the end of a small contour cylindrical part 25 of the base member 20, forming a fluid chamber in the inside. While an orifice forming member 50 is connected to the small contour cylindrical part 25 by a new elastic member 60 of relatively small area consisting of rubber material and different from said elastic member 30. The inside of the fluid chamber 2 is divided into two chambers 3, 4 by the elastic member 60, and these chambers are communicated with each other through orifices 51. A moving amount of fluid becomes a value subtracting a moving amount of fluid by the elastic member 60 from a moving amount of fluid by the elastic member 30, and the value can be decreased so as to enable a loss coefficient to be set to an ideal value. |
