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
