To restrict steering angle of an outboard engine propelling unit in high speed traveling of a vessel when a hydraulic pressure driving type steering device for having the outboard engine propulsion unit carry out a turning action by using hydraulic pressure.SOLUTION: A first steering angle restriction piston 53 and a second steering angle restriction piston 63 are at least activated so that a restricted state when movement is restricted to stroke end of a first steering angle changing piston 33 and a second steering angle changing piston 43 when vessel speed is equal to or more than vessel speed to be subjected to steering angle restriction. According to the method, steering of an outboard engine propulsion unit is carrying out in a state of having restriction on the steering angle by having a rack and pinion mechanism 71 driven along with reciprocating movement of the first steering angle changing piston 33 and the second steering angle changing piston 43 in a state of having respective movements of the first steering angle changing piston 33 and the second steering angle changing piston 43 restricted to respective stroke ends.SELECTED DRAWING: Figure 4

    【課題】油圧を用いて船外機推進ユニットを旋回動作させる油圧駆動式の船舶用操舵装置を採用した場合において、船舶の高速走行時における船外機推進ユニットの操舵角の制限を行うこと。【解決手段】第1操舵角制限用ピストン53及び第2操舵角制限用ピストン63は、船速が操舵角制限適用船速以上である場合には、第1操舵角変更用ピストン33及び第2操舵角変更用ピストン43のストロークエンドまでの移動を規制する規制状態となるように少なくとも動作されている。これによれば、第1操舵角変更用ピストン33及び第2操舵角変更用ピストン43それぞれのストロークエンドまでの移動が規制された状態で、第1操舵角変更用ピストン33及び第2操舵角変更用ピストン43の往復動に伴ってラックアンドピニオン機構71が駆動することで、操舵角の制限が行われた状態での船外機推進ユニットの操舵が行われる。【選択図】図4
