In order to control the peak and frequency of antiresonance in inversion type-specific resonance generated in intermediate- and high-frequency areas in an inverted liquid-sealed engine mount, in an inverted liquid-sealed engine mount with a sub-liquid chamber (7) facing upward, an insulator (8) protrudes in a mountain shape into a main liquid chamber (6), and a resistor (11) is provided in an annular recessed portion (10) formed around the insulator. The resistor (11) is inserted and mounted in a fitting recessed portion (24) of a lining layer (22) and elastically supported by a rib (23), and is movable by liquid that flows through the annular recessed portion (10) in a circumferential direction. An adjustment gap (12) is present between the resistor (11) and the insulator (8), and inversion type- specific resonance is produced by the passage of the liquid therethrough, but since the resistor (11) is movable, the peak of antiresonance lowers and the frequency moves. |
