PROBLEM TO BE SOLVED: To provide a friction reduction device of a ship which improves friction resistance reduction effect while making simplification of the structure.SOLUTION: A friction reduction device of a ship comprises: a gas chamber 41 arranged inside of a ship hull 10; a bottom plate 27 which is a partition between inside of the gas chamber 41 and outside of the ship hull 10; a plurality of air outlet ports 42 arranged in the bottom plate 27; a compressor 43; an auxiliary air supply pipeline 46 by which the compressor 43 communicates with the gas chamber 41 in which a passage area of the auxiliary air supply pipeline communicated with the gas chamber 41 is smaller than an aperture area of the air outlet port 42; and a coated plate 64 which is arranged facing the air outlet ports 42 in which a communication passage P exists between the coated plate and the bottom plate 27.SELECTED DRAWING: Figure 4

    【課題】船舶の摩擦低減装置において、構造の簡素化を図ると共に摩擦抵抗低減効果の向上を図る。【解決手段】船体10の内部に設けられる気体室41と、気体室41内と船体10の外方とを仕切る船底外板27と、船底外板27に設けられる複数の空気吹き出し口42と、圧縮機43と、圧縮機43と気体室41とを接続して気体室41へ連通する通路面積が空気吹き出し口42の開口面積より小さい面積に設定される副空気供給通路46と、船底外板27との間に連通路Pを介して空気吹き出し口42に対向して配置される被覆板64とを設ける。【選択図】図4
