PURPOSE: A device for reducing vibrational exciting force from a propeller is provided to remarkably reduce fluid pressure from a propeller and shock applied to a ship since fluid pressure, caused by the rotation of a propeller, is disturbed by the fluid flowing out of a fluid inlet pipe. CONSTITUTION: A device for reducing vibrational exciting force from a propeller comprises a fluid inlet pipe(20), an inlet port(22) and a discharge port(24). The fluid inlet pip is installed on the bottom of the stern of the ship. The inlet port is formed toward the floor on the bottom of the stern of the ship so that fluid can flow into as the ship moves. The discharge port is formed toward the upper part of the propeller so that the fluid flowing into through the inlet port is discharged to the upper part of the propeller through the fluid inlet pipe and the fluid pressure due to the rotation of the propeller is disturbed. One or more fluid inlet pipe are installed on the bottom of the stern of the ship.
