PURPOSE: A fluid mount of a vehicle is provided to effectively reduce vibration noise produced when the engine of the vehicle is turned on and off and the vehicle travels at constant speed and at high speed, and to improve NVH(Noise Vibration Harshness) performance of the vehicle by making fluid filled in a mounting rubber smoothly flow by forcible force. CONSTITUTION: A fluid mount of a vehicle comprises a mounting rubber(21) forming a fluid space(21a) inside; an engine mounting stopper(22) one end of which is forcibly fitted into the upper inside of the mounting rubber and the other end of which is combined to an engine side; a vehicle body mounting stopper(23) combined to a vehicle body side while covering the outer peripheral surface and the lower end portion of the mounting rubber; a first partition plate member(25) fixed to the lower end side of the fluid space, to divide the fluid space into a lower space part(21b) and an intermediate space part(21c); a second partition plate member(26) fixed on the first partition plate member, to divide the intermediate space part into the intermediate space part and an upper space part(21d); a rotating pin(27) rotatably installed through the middle of the second partition plate member; first rotating vanes(28) combined to one end of the rotating pin and disposed in the intermediate space part; and second rotating vanes(29) combined to the other end of the rotating pin and disposed in the upper space part. The first partition plate member forms a decoupler(24) in the middle part to give stiffness and forms plural fluid holes, connecting the lower space part and the intermediate space part, and first orifices(25b) connected to the intermediate space part. The second partition plate member forms second orifices(26a) connecting the intermediate space part and the upper space part.
