PROBLEM TO BE SOLVED: To prevent a damage on a neutral brake which is caused by high-speed idling of a propeller during, for example, coasting navigation, towing for net winding up, and the like.SOLUTION: There are provided a forward backward switching mechanism for switching a rotational power of a main engine mounted on a ship into an output of forward, neutral or backward, an output shaft which transmits an output from the forward backward switching mechanism to a propeller, and a neutral brake for braking the output shaft at the neutral of the forward backward switching mechanism. There are further provided a neutral switch 51 for detecting a neutral state of the forward backward switching mechanism, a rotational speed detection sensor 52 for detecting rotational speed of the output shaft, and a controller which switches the neutral brake between a braking state and a release state based on the detection information of the neutral switch 51 and the rotational speed detection sensor 52.SELECTED DRAWING: Figure 7

    【課題】例えば惰行航行時や網巻き上げの曳航時等において、前記プロペラの高速遊転による前記中立ブレーキの損傷を防止できるようにする。【解決手段】船舶に搭載した主機関の回転動力を前進、中立又は後進の出力に切り換える前後進切換機構と、前後進切換機構からの出力をプロペラに伝達する出力軸と、前後進切換機構の中立時に出力軸を制動させる中立ブレーキとを備える。前後進切換機構の中立状態を検出する中立スイッチ51と、出力軸の回転速度を検出する回転速度検出センサ52と、中立スイッチ51及び回転速度検出センサ52の検出情報に基づき中立ブレーキを制動状態と解除状態とに切り換えるコントローラとを更に備える。【選択図】図7
