PROBLEM TO BE SOLVED: To provide a fluid filled vibration control device having novel construction for developing vibration control effects as intended during vibration input in the axial direction and developing vibration control effects based on the flowing operation of fluid on vibration in different frequency regions in the direction perpendicular to the axis. SOLUTION: On both sides of a first mounting member 12 across a supporting shaft part 20 in the direction perpendicular to the axis, a pair of operating liquid chambers 94, 94 are provided for producing mutually opposite positive and negative pressure fluctuations during vibration input in the direction perpendicular to the axis. Non-compressive fluid is filled in the pair of operating liquid chambers 94, 94, and the pair of operating liquid chambers 94, 94 are communicated with each other via a low frequency orifice passage 106 which is tuned into a low frequency region and a high frequency orifice passage 116 which is tuned into a high frequency region. In the high frequency orifice passage 116 at an opening porion of at least one of the pair of operating liquid chambers 94, 94, a movable member 118 is arranged for restricting the flow amount of fluid through the high frequency orifice passage 116.
