A fluid-filled active vibration damping device including: (a) an elastsic body which elastically connects first and second mounting members and which partially defines a fluid chamber filled with a non-compressible fluid; (b) an oscillating member which partially defines the fluid chamber; (c) an electromagnetic actuator for oscillating the oscillating member; (d) a stabilizing member which is disposed on the side of the oscillating member that is remote from the fluid chamber, and which is opposed to and spaced apart from the oscillating member in an oscillation direction of the oscillating member; (e) first and second elastic supports through which the respective oscillating and stabilizing members are elastically supported by the second mounting member; and (f) a connecting member which connects the oscillating and stabilizing members, so as to provide a displaceable assembly which is displaceable relative to the second mounting member.
