To provide a vessel propulsion device capable of reducing resistance when directly advancing in front to back direction while including a function for generating a force working on vessel width direction.SOLUTION: A vessel propulsion device includes: a duct provided on a bottom of a hull, having a plurality of side plates extending in front to back direction of the hull as well being provided with spacing in vessel width direction, and formed with flow paths extending in the front to back direction in between adjacent side plates; a plurality of propellers respectively provided in each flow path and generating a front to back direction flow in the flow paths; and a plurality of rudders provided to be capable of revolving around an axis line extending in the vertical direction along rear edges of respective side plates and extending in the radial direction of the axis line.SELECTED DRAWING: Figure 5

    【課題】船幅方向にはたらく力を発生させる機能を備えつつ、前後方向直進時の抵抗を低減することができる船舶推進装置を提供する。【解決手段】船舶推進装置は、船体の底部に設けられ、船体の前後方向に延びるとともに船幅方向に間隔あけて設けられた複数の側板を有し、隣り合う側板同士の間に前後方向に延びる流路が形成されたダクトと、各流路にそれぞれ設けられて、流路内に前後方向の流れを発生させる複数のプロペラと、各側板の後縁に沿って上下方向に延びる軸線回りに回動可能に設けられて、軸線の径方向に延びる複数の舵と、を備える。【選択図】図5
