To provide a structure which enables reduction of vibration in a wide frequency range and achieves excellent durability in a vibration control device which controls vibrations of an engine for a ship.SOLUTION: A vibration control device 100 is disposed between a ship body 2 and a propulsion engine 4. The vibration control device 100 includes a lower plate 11, an upper plate 21, a coil spring 40, and a vibration damping member 30. The lower plate 11 is fixed to the ship body 2 side. The upper plate 21 is disposed above the lower plate 11 and fixed to the propulsion engine 4 side. The coil spring 40 is disposed between the lower plate 11 and the upper plate 21. The vibration damping member 30 is disposed between the lower plate 11 and the coil spring 40 or between the upper plate 21 and the coil spring 40 and is formed including a metal plate 32 and a damping plate 31 formed by a damping material. The metal plate 32 is located between the coil spring 40 and the damping plate 31.SELECTED DRAWING: Figure 2
