PROBLEM TO BE SOLVED: To facilitate assembly of a partition part by a plurality of constitution parts without the occurrence of displacement in a position in air, to reduce relative displacement of the constitution parts due to a change with the lapse of time, to perform excellent seal between the parts, and to improve durability. SOLUTION: A partition part 10 is fitted in a space between a vibration control body 2 and a diaphragm 4, which are intercoupled through a body fitting 1. The partition part is formed such that a second diaphragm 11 is situated on the main liquid chamber 7 side of a partition main member 15 to form a first orifice 13, a partition plate member 16 to press a peripheral edge part to form a second auxiliary liquid chamber 9 and a second orifice 14 is engaged with and covered by the outer periphery of the partition main member by a caulking means, a support plate 17 for partition is fixed on the under surface side of the partition main member 15 by a press-in means and fitted in the inner periphery of a body fitting 1, and the outer peripheral edge part of the support plate is securely fixed at the body fitting. |
