PROBLEM TO BE SOLVED: To provide an active liquid sealed vibration absorbing device having simplified construction with its increased output and contributing to a smaller size with a less number of parts. SOLUTION: The vibration absorbing device comprises a first mounting tool 1 and a second mounting tool 3 connected to each other via a vibration absorbing base 3, a rubber wall 5 provided on the second mounting tool 2 to form a first liquid chamber 4, a diaphragm 7 forming a second liquid chamber 6 as part of a chamber wall, the first liquid chamber 4 and the second liquid chamber 6 being communicated with each other via an orifice 8, and an iron core movable type actuator 9 constructed as part of a needle 30 which can reciprocate a shaft member 27 connected to the rubber wall 5 in the axial direction in relation to a stator 28. A coil 33 of the stator 28 is excited for driving the shaft member 27 in both outward and homeward strokes to vibrate the rubber wall 5, whereby pressure in the first liquid chamber 4 is controlled.
