PURPOSE:To improve the damping force by pressing an elastic member dividing a fluid chamber at the time of contraction of a great dispalcement for raising a fluid pressure inside the fluid chamber compulsorily for increasing the flow passing through an orifice. CONSTITUTION:A projection 31 is formed at a lower part on an outer wall of a reverse-umbrella-shaped share spring rubber 30 in one body. When an engine mount 1 is contracted by a great displacement, the projection 31 is pressed on an upper face of a fixing flange 12 to press the share spring rubber 30 to the inner side of a fluid chamber 2 at the same time. A pressure is compulsorily raised on the fluid inside the fluid chamber 2, and consequently, the discharge flowing into a diaphragm chamber 41 passing through an orifice is increased to improve the damping force. |
