PROBLEM TO BE SOLVED: To provide a liquid-filled type vibration-proofing device constituted of a small number of part items reducing a vibration at a plurality of frequency areas. SOLUTION: This liquid-filled type vibration-proofing device 2 has a rubber elastic body 8 for connecting mounting members 4, 6 each other; a first diaphragm 12 forming a liquid chambers 14 between the rubber elastic body 8 and it, a first partition member 16 for partitioning the liquid chamber 14 to a main liquid camber 18 and a first sub-liquid chamber 20, a second partition member 32 having a projection 50 projected to the main liquid chamber 18 and press-fitted into the first partition member 16, a second diaphragm 42 clamped and fixed by the first partition member 16 and the second partition member 32, a second sub-liquid chamber 44 positioned in the first partition member 6; a first orifice passage 26 for communicating the main liquid chamber 2/18 with the first sub-liquid chamber 20, and a second orifice passage 48 for connecting the main liquid camber 18 with the second sub-liquid chamber 44. A tip end of the projection 50 is opposed to the robber elastic body 8 at a predetermined interval. |
