PURPOSE: To keep a dynamic constant lower and provide sufficient damping. CONSTITUTION: A fluid mount is provided with an elastic body 7 elastically connecting two fixing sections 3 and 5, two fluid chambers 11 and 13 which are provided between the two fixing sections 3 and 5 and filled with fluid, a communication hole 17, which communicates the fluid chambers 11 and 13 and a mass body 21, which forms orifices 19 in the gap between, and the internal faces 17a, which are vibrationably and elastically supported to the communication hole 17. For this reason, when the mass body 21 resonates along the axial direction of the communication hole 17, in the area of smaller frequency than the resonant frequency of the mass body 21, effective orifice length is lengthened, and in the area exceeding the resonant frequency of the mass body 21, effective orifice length is shortened. |
