PROBLEM TO BE SOLVED: To control the peak and frequency of antiresonance in inversion type-specific resonance produced in intermediate- and high-frequency areas in an inverted liquid-sealed engine mount.SOLUTION: In an inverted liquid-sealed engine mount with a sub-liquid chamber 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. |
