PURPOSE:To provide a fluid-sealed type mount device equipped with a driving means which can exert a large vibration force to a vibrating plate for controlling the internal pressure of a fluid chamber. CONSTITUTION:Behind a vibrating plate 27 which constitutes a part of the wall part of a fluid chamber 32, a yoke member 50 having an annular gap part 62 opened to the vibrating plate 27 side is arranged, and a plurality of permanent magnets 58 and 60 which extend in the circumferential direction are arranged at least on one side of the opposed surfaces in the radial direction in the gap part C 62, separated in the axial direction, and a magnetic path is formed. On the gap part 62 on the magnetic path, a ring shaped movable coil 68 which extends in the circumferential direction, keeping the length in the axial direction, riding over between the arrangement parts of a plurality of permanent magnets 58 and 60 is arranged in shiftable manner in the axial direction, and connected with the vibrating plate 27, and then the vibrating plate 27 is vibrated by the electric charge on the movable coil 68. |
