PROBLEM TO BE SOLVED: To exert a stable vibration control characteristic by restraining variation of a distance between a pair of partition plates. SOLUTION: This liquid-sealed vibration control device 10 is provided with a first mounting means 12, a second mounting means 14, a vibration control base body 16, a diaphragm 29, a partition body 30, and an orifice 32. The partition body is composed of an annular orifice formation member 34, a rubber wall 36 closing a space of its inside surface 34A, and a pair of partition plates 38 and 40 sandwiching the rubber wall in the axis direction X, and the pair of partition plates are connected through a connection part 50 penetrating a through-hole 48 of the rubber wall 36. The connection part 50 comprises: facing surface parts 56 and 58 respectively formed on the pair of partition plates, and facing to each other in the axis direction X; an engagement projection part 60 projected in the axis direction X on the one-side partition plate 38; and an engagement hole part 62 formed on the other-side partition plate 40, and receiving the engagement projection part; and the engagement projection part 60 inserted into the engagement hole part 62 is held to the engagement hole part 62 so as not to be extracted in a state where the facing surface parts 56 and 58 face each other.
