Claims (1)
- 船舶用エンジンの駆動力が伝達される駆動軸に固着された駆動ベベルギアと、
前記駆動軸と同軸の軸線に直交して設けられたプロペラ軸と、
前記プロペラ軸に同軸にそれぞれ回動自在に設けられかつ互いに逆回転するように前記駆動ベベルギアに噛み合わされた一対の被動ベベルギアと、
前記プロペラ軸と前記駆動ベベルギアおよび前記被動ベベルギアとを受容するギアケースと、
前記プロペラ軸と一体回転しかつ前記プロペラ軸の軸線方向に変位することにより前記一対の被動ベベルギアに対して一方に選択的に係合または両方に非係合可能に設けられたクラッチ部材と、
前進・後進・停止の3状態を手動操作により選択することにより前記クラッチ部材を当該選択状態に応じて前記係合または前記被係合の対応する位置に変位させるべく設けられたシフト軸とを有する船舶用推進装置であって、
前記エンジンの出力軸により駆動されかつ潤滑油供給用に用いられているオイルポンプと、
前記ギアケース内に設けられ、前記クラッチ部材に固着されかつ前記プロペラ軸と同軸的に変位自在に設けられたスライドロッドを有し、前記オイルポンプからの油圧により当該スライドロッドを変位させることにより前記クラッチ部材を変位させる補助駆動力を発生する油圧アクチュエータとを有し、
前記スライドロッドの前記プロペラ軸側とは相反する前端から軸線方向前方に突出するラックが設けられ、
前記シフト軸が、前記ギアケース内で上下に延在しかつ回動自在に設けられていると共に、下端に前記ラックに噛合するピニオンを備え、
前記シフト軸に、前記オイルポンプから前記油圧アクチュエータに至る油路の一部と、前記手動操作による前記シフト軸の回動により前記油路の連通と非連通との2状態を選択する切替油路とが設けられていることを特徴とする船舶用推進装置。
