PROBLEM TO BE SOLVED: To provide a fluid sealed vibration absorbing device having a new structure capable of achieving a fluid pressure absorbing mechanism with a small number of components and a simple structure and of effectively obtaining vibration absorbing effects both by a flow action of fluid made to flow through an orifice passage and by a fluid pressure absorbing action of the fluid pressure absorbing mechanism. SOLUTION: In the fluid pressure absorbing mechanism, a first support rubber elastic body 38 is formed by axially extending an outer peripheral portion of a main body rubber elastic body 16 on an inner peripheral face of a second mounting member 14, and an outer peripheral edge part of a partition member 70 is overlapped with an axial end face of the first support rubber elastic body 38 in the position separated inwardly from the second mounting member 14. A second support rubber elastic body 56 fixed to the second mounting member 14 is provided and overlapped with the outer peripheral edge part of the partition member 70 from the side opposite to the first support rubber elastic body 38. By sandwiching the partition member 70 between the support rubber elastic bodies 38, 56, pressure fluctuation of a pressure receiving chamber 75 is released to an equilibrium chamber 76 and absorbed.
