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
