PROBLEM TO BE SOLVED: To provide a liquid encapsulation type vibration control device easily assembled without influencing the shape or dimensions of a caulking part and without impairing the mounting easiness and reliability, capable of improving the vibration control performance for the low-frequency range and the middle/ high frequency range. SOLUTION: A body fitting 2 and a first mounting fitting 4 are coupled together through a vibration control base 3 made of rubber, and a liquid encapsulation chamber between this base 3 and first diaphragm 5 fixed to the body fitting 2 is partitioned by a partitioning member 10 into two liquid cambers 8a and 8b, mutually communicated via orifices. The partitioning member 10 is composed of a partitioning plate piece 11 to form a first orifice, a rubber orifice member 12 provided at the inside surface of the piece 11, and an insert piece 13 fixed to the piece 11 and contacted with the rubber orifice member 12, wherein a second orifice 17 is formed in the rubber orifice member 12 with one end left open to the liquid chamber 8a and other end blocked with a second diaphragm 19, and caulking is made fast to the body fitting 2 together with the first diaphragm and a second mounting fitting. |
