PROBLEM TO BE SOLVED: To provide an engine vibration damping device capable of improving vibration damping effect.SOLUTION: An engine vibration damping device 100 supporting an engine 10 to a hull 61 with a coil spring 110 and a thin plate 120 includes: a circuit 160 including a piezoelectric element 130 affixed to the thin plate 120, a resistor R, and a switch S; and an ECU 50 for controlling opening and closing timing of the switch S. The ECU 50 closes the switch S when the engine 10 is operated at engine speed lower than prescribed engine speed, and opens the switch S when the engine 10 is operated at engine speed equal to or higher than the prescribed engine speed.SELECTED DRAWING: Figure 4

    【課題】防振効果を向上できるエンジン防振装置を提供する。【解決手段】エンジン10を船体61に対してコイルばね110及び薄板120によって支持するエンジン防振装置100であって、薄板120に貼設された圧電素子130と、抵抗Rと、開閉器Sとを含んだ回路160と、開閉器Sの開閉タイミングを制御するECU50と、を備え、ECU50は、エンジン10が所定回転数未満で運転する場合には、開閉器Sを閉とし、エンジン10が所定回転数以上で運転する場合には、開閉器Sを開とする。【選択図】図4
