To provide a liquid-sealed type vibration control device capable of improving productivity when a diaphragm is held in a partition body partitioning a liquid chamber.SOLUTION: A liquid-sealed type vibration control device includes: a first fixture and a cylindrical second fixture; a vibration control substrate; a first diaphragm; a partition body partitioning a liquid chamber into a first liquid chamber on the vibration control substrate side and a second liquid chamber on the first diaphragm side, and forming a third liquid chamber in an inside thereof; a first orifice communicating the first liquid chamber with the second liquid chamber; and a second orifice communicating the first liquid chamber or the second liquid chamber with the third liquid chamber. The partition body includes a second diaphragm made of a plate-like elastic body and forming a part of a wall surface of the third liquid chamber, and a first member and a second member fixed with each other while having the second diaphragm therebetween.SELECTED DRAWING: Figure 1

    【課題】液室を仕切る仕切体の内部にダイヤフラムが保持される場合に生産性を向上できる液封入式防振装置を提供すること。【解決手段】液封入式防振装置は、第1取付具および筒状の第2取付具と、防振基体と、第1ダイヤフラムと、液室を防振基体側の第1液室と第1ダイヤフラム側の第2液室とに仕切って内部に第3液室が形成される仕切体と、第1液室と第2液室とを連通する第1オリフィスと、第1液室または第2液室と第3液室とを連通する第2オリフィスと、を備える。仕切体は、第3液室の壁面の一部を形成する平板状の弾性体製の第2ダイヤフラムと、第2ダイヤフラムを間に挟んで互いに固定される第1部材および第2部材とを備える。【選択図】図1
