PROBLEM TO BE SOLVED: To improve friction resistance reduction effect in a friction reduction device of a ship.SOLUTION: A friction reduction device of a ship is provided with: a gas chamber 41 provided in a ship body; a division wall which divides the interior of the gas chamber 41 from the exterior of the ship body; an air outlet port 42 provided at a ship bottom outer plate 27 provided on the division wall; and a first guide plate 51 which is provided at the rear side of the ship body 10 in the air outlet port 42 and serves as a guide plate. In the structure, air, which is blown from the gas chamber 41 into water at the ship body exterior through the air outlet port 42, is flowed to the rear side of the ship body 10 by the guide member 51 and is less likely to move away from an outer surface of the ship body 10 or diffuses into a wide range. Thus, the surface of the ship body 10 is properly covered with air bubbles to improve friction resistance reduction effect. |
