PROBLEM TO BE SOLVED: To realize the sealing property of a combinational part of a plurality of members constituting a partition member by means of a simple structure and with advantage and superior durability in a fluid-filled vibration isolator formed by partitioning a main liquid chamber and a sub liquid chamber and having the partition member for supporting a movable rubber plate for allowing or controlling fluid flow based on elastic deformation. SOLUTION: A partition member 38 is constituted by axially superposing combinational bodies 44, 46 on a supporting fitting 42 having a cylidrical seating part 54 in which the outer periphery edge part of a movable rubber plate 40 is vulcanized and stuck. Meanwhile, a sealing rubber layer 60 is provided on the inner periphery surface of the seating part 54 of the supporting fitting 42. Fitted parts 66, 84 to be fitted in the fitting part 54 of the supporting fitting 42 are formed in the combinational bodies 44, 46. Diametrical constraction is applied to the fitting part 54 of the supporting fitting 42. The sealing rubber layer 60 is sandwiched between the fitted parts 66, 84 of the combinational bodies 44, 46 for fluid-tight filling and fixation. |
