PURPOSE: A liquid sealing mounting device for supporting engine allows the cross sectional area and the length of a flow path formed on an orifice member to be variously altered, thereby improves the damping performance of vibration and noise. CONSTITUTION: A liquid sealing mounting device for supporting engine comprises an orifice member(8) having a cylinder member(10) and a cylindrical case(11). The cylinder member(10) has a screw type slot on the outer periphery thereof. The cylindrical case(11) fitted on the outer surface of the cylinder member(10) forms a flow path(9) with the screw type slot. The cross sectional area and the total length of the flow path(9) is determined by the variation of the pitch and the lead angle of the screw type slot, thereby enabling the optimized design of the flow path(9).
