PURPOSE: A fluid mounting of a vehicle engine is provided to reduce noise and vibration within the entire frequency band by installing a gas chamber filling gas in the upper part of an outer case. CONSTITUTION: A fluid mounting of an engine for a vehicle is composed of an outer case(11) combined with a vehicle body by a bolt, opened in the upper part, divided into upper and lower parts by a partition having a first orifice, and filled with fluid; a rubber member(16) closing the upper part of the outer case; and a gas chamber(17) installed in the middle of the rubber member to close the upper part of the outer case, combined with an engine bracket by the bolt, connected to the upper part of the outer case, and filled with insoluble gas. Vibration at high frequency band is reduced with installing the gas chamber in the middle of the rubber member. Noise and vibration within the range of various frequency by mounting the gas chamber.
