PROBLEM TO BE SOLVED: To provide a fluid-sealed type vibration control device with a novel structure, which allows a partition member made of synthetic resin with low strength to be fitted and fixed in a second attachment member easily, and avoids a defect upon assembly due to errors of dimensions in the partition member or the second attachment member. SOLUTION: In this fluid-sealed type vibration control device, a seal rubber 36 is fixed in the inner circumferential surface of the second attachment member 14, an annular step 38 is formed in the inner circumferential surface of the seal rubber 36, and the inner circumferential surface of the seal rubber 36 is made as an inner circumference taper surface 44 expanded wider than the step 38 toward an opening side opposite a rubber elastic body of a main body 16 in the opposite side of the rubber elastic body 16. The outer circumferential surface of the partition member 50 formed of hard synthetic resin is made as an outer circumference taper surface 62 corresponding to the inner circumference taper surface 44, the partition member 50 is fitted in the second attachment member 14 to make the outer rim section on the front edge side of the partition member 50 abut on the step 38, and the outer circumference taper surface 62 is closely contacted with the inner circumference taper surface 44, thereby allowing the partition member 50 to be positioned and assembled to the second attachment member 14.
