Summary:PROBLEM TO BE SOLVED: To provide a technology that enables reduction of an installation space of a rudder in a ship.SOLUTION: A pusher propeller 3 is provided at a stern part 1a of a ship 1. The pusher propeller 3 is attached to the stern part 1a of a ship body so as to rotate around a rotation axis C1. The pusher propeller 3 has: a rotation center part 3a in which its center axis C1 is set to the rotation axis C; and multiple propeller blades 3b which are disposed in a direction around the rotation axis C1 and coupled to the rotation center part 3a. A front portion of the rotation center part 3a is rotatably supported by the stern part 1a. The pusher propeller 3 is rotationally driven around the rotation axis C1 in water to generate an advance thrust force of the ship 1. A rudder structure 10 includes a rudder 5 provided behind the pusher propeller 3. A recess 9 recessed to a rear side is formed at a front end 5a of the rudder 5. A rear end part 3a1 of the rotation center part 3a of the pusher propeller 3 is disposed in the recess 9.SELECTED DRAWING: Figure 1 【課題】船において舵の設置用スペースを減らせる技術を提供する。【解決手段】船1の船尾部1aには推進プロペラ3が設けられる。推進プロペラ3は、回転軸C1まわりに回転可能に船体の船尾部1aに取り付けられている。推進プロペラ3は、回転軸C1を中心軸とする回転中心部3aと、回転軸C1まわりの方向に配置され回転中心部3aに結合されている複数のプロペラ翼3bとを有する。回転中心部3aの前側部分は船尾部1aに回転可能に支持されている。推進プロペラ3は、回転軸C1まわりに水中で回転駆動されて、船1の前進推力を発生させる。舵構造10は、推進プロペラ3の後方に設けられた舵5を備える。舵5の前端5aには、後方への窪み9が形成されている。この窪み9に、推進プロペラ3の回転中心部3aの後端部3a1が配置される。【選択図】図1
