PURPOSE:To facilitate management of the seal part and simplify the assembling works by devicing well the mounting structure of a diaphragm and a partition in a liquid chamber in a vibration control mount of liquid enclosed type, and thereby lessening the seal structures. CONSTITUTION:A liquid chamber 4 is formed by mounting a vibration control base 2 at one of the openings of a body metal piece and also a diaphragm 3 at the other opening and partitioned into a plurality of chambers 4a, 4b by a partition(s) 10, and these chambers 4a, 4b are put in communication through an orifice 5 provided in the partition 10 so that a vibration control mount of liquid enclosed type is formed. The partition 10 is composed of a ring-shaped orifice formation part 12 having a groove 11 to work as an orifice located at the periphery and a partitioning plate part 13 which blocks the space inside the part 12, wherein the diaphragm 3 is attached to the part 12 by means of a vulcanization molding, and the partition 10 is fitted on the body metal piece 1 so that the diaphragm 3 is fitted opposing to the base 2 while the partition 10 is pinched. |
