PROBLEM TO BE SOLVED: To provide a fluid-sealed vibration control device having a new structure, which stably provides a desired vibration isolation effect by increasing the degree of freedom of design while downsizing it. SOLUTION: A body rubber elastic body 16 is fixed to an opening peripheral part on a small-diameter part 26 side of a second mounting member 14 having a stepped cylindrical shape; an opening on a large-diameter part 28 side is covered with a lid member 60; an opening window 36 formed over the large-diameter part 28 from a step part 24 is closed by a flexible rubber film 44 formed integrally with the body rubber elastic body 16; an orifice member 62 is projected from the lid member 60 toward the step part 24 of the second mounting member 14; and, by fluid-tightly bringing a projection part of the orifice member 62 into contact with the inside edge part of the step part 24, a pressure reception chamber 72 and an equilibrium chamber 74 are formed on the inner periphery side of the orifice member 62 and on the outer periphery side thereof, respectively, and an orifice passage 78 is formed to extend in the circumferential direction.
