Claims

[Scope of utility model registration request]

In a ship equipped with a diesel engine as the main engine, with the crankshaft facing toward the ship's ship, the engine rotates within the longitudinal section of the ship at angular velocities of 1 and 2 times the speed of the crankshaft, respectively, in conjunction with the crankshaft. A ship equipped with a vibration damping device characterized by being equipped with a number of rotating weights.
