PROBLEM TO BE SOLVED: To provide an active vibration damping device capable of securing vibration damping performance.SOLUTION: A piston member 30 is electromagnetically driven by an actuator 40, and vibration is suppressed by changing a volume of a first liquid chamber 17a. The actuator 40 generates a reaction force against thrust generated on the piston member 30 by internal pressure of the first liquid chamber 17a changed by deformation of a vibration isolation base 15. As movement of the piston member 30 in changing the internal pressure of the first liquid chamber 17a can be suppressed, change of the volume of the first liquid chamber 17a due to displacement of the piston member 30 is suppressed, and predetermined damping performance can be secured.SELECTED DRAWING: Figure 1

    【課題】防振性能を確保できる能動型防振装置を提供すること。【解決手段】アクチュエータ40により電磁力でピストン部材30を駆動させ、第1液室17aの容積を変化させて振動を抑制する。アクチュエータ40は、防振基体15の変形により変化した第1液室17aの内圧でピストン部材30に生じる推力に抗する反力を発生する。第1液室17aの内圧が変化したときのピストン部材30の移動を抑制できるので、ピストン部材30の変位による第1液室17aの容積変化を抑制し、予め設定された防振性能を確保できる。【選択図】図1
