To provide a steering gear generating great propulsion force when having a vessel directly advance, great braking force when making an emergency stop, and capable of reducing noise and oscillation generated in starboard or port.SOLUTION: A port side rudder is formed from a first left rudder unit 10 extending in the vertical direction and a second left rudder unit 11 extending to the right side from a top unit, a port side shaft 12 is erected on the right extending in the vertical direction, a starboard side rudder is formed from a first right rudder unit 20 extending in the vertical direction and a second starboard unit 21 extending to the left side from the top thereof, a right rudder shaft 22 is erected extending in the vertical direction on the left thereof, the left rudder shaft and the right rudder shaft are provided on the outer periphery of a propeller or on an upstream side of the outer periphery of the propeller in a plan view, structured so that port and starboard side rudders are in a direct advance stance which is in parallel with a virtual line extending in the front to back direction when directly advancing and the port and starboard rudders are in an emergency stop stance orthogonal to the virtual line extending in the front to back direction in an emergency stop, and a left slit 14B extending on the top of the first port unit and a right slit 24B extending on the top of the first starboard unit are provided.SELECTED DRAWING: Figure 6

    【課題】船を直進させる場合には大きな推進力を、緊急停止する場合には大きな制動力を発生し、取舵時や面舵時に発生する騒音や振動を低減できる操舵装置を提供する。【解決手段】左舷側舵を上下方向に延在する第1左舵部10と、上部から右側に延在する第2左舵部11で形成し、右部に上下方向に延在する左舵軸12を立設し、右舷側舵を上下方向に延在する第1右舵部20と、その上部から左側に延在する第2右舵部21で形成し、その左部に上下方向に延在する右舵軸22を立設し、平面視において、左舵軸と右舵軸をプロペラの外周部又はプロペラの外周部よりも上流側に設け、直進時には、左右舷側舵を前後方向に延在する仮想線と平行な直進姿勢にし、緊急停止時には、左右舷側舵を前後方向に延在する仮想線に直交する緊急停止姿勢の構成とし、第1左舵部の上部に延在する左スリット14Bを、第1右舵部の上部に延在する右スリット24Bを設けた。【選択図】図6
