PROBLEM TO BE SOLVED: To provide a liquid sealed vibration control device having restricted dynamic spring operation in a higher frequency region. SOLUTION: The liquid sealed vibration control device comprises a first mounting tool 1, a cylindrical second mounting tool 2, a vibration control base 3, a diaphragm 9 forming a liquid filling chamber 8 between the vibration controling base 3 and itself, a partition body 12 for partitioning the liquid filling chamber 9 into a first liquid chamber 11A on the side of the vibration controling base 3 and a second liquid chamber 11B on the side of the diaphragm 9, and an orifice 25 for communicating the first liquid chamber 11A with the second liquid chamber 11B. The partition body 12 consists of a partition plate 15 and a supporting portion 31 for supporting the partition plate 15. It is constructed so that the partition plate 15 is reciprocative relative to the supporting portion 31 and deformable with the input of vibration. An elastic body 29 is laid between the inner periphery of the second mounting tool 2 and the supporting portion 31, and the partition body 12 is elastically supported by the second mounting tool 2. A stirring plate 60 is provided in the first liquid chamber 11A, and a first liquid chamber side orifice 63 is formed between an outer peripheral edge 61 of the stirring plate 60 and an inner peripheral face 62 of the first liquid chamber 11A.
