To provide a steering gear with a driving means capable of smoothly turning a rudder plate in the entire range of a steering angle.SOLUTION: The driving means consists of the steering shaft extending in the vertical direction to support the rudder plate, the connection arm extending in a radial direction of the steering shaft, the supporting shaft extending in the vertical direction at the tip of the connection arm, and a pair of hydraulic cylinders the rod tip of which is rotatably fixed around the supporting shaft, and the shaft center in the longitudinal direction of either one of the hydraulic cylinders is set along the tangent of the rotation trajectory of the supporting shaft rotating around the steering shaft when the rudder plate is in a state between a neutral attitude and a maximum steering angle attitude.SELECTED DRAWING: Figure 3
【課題】舵角の全域において舵板をスムーズに回動させることができる駆動手段を備える操舵装置を提供する。【解決手段】駆動手段を、舵板を支持する上下方向に延在する舵軸と、舵軸の径方向に延在する連結アームと、連結アームの先端部に上下方向に延在する支軸と、支軸にロッド先端部を回転自在に固定した一対の油圧シリンダで構成し、舵板が中立姿勢状態から最大舵角姿勢状態の間に、いずれか一方の油圧シリンダの長手方向の軸心が、舵軸を中心として回動する支軸の回転軌跡の接線に沿って設ける。【選択図】図3
