To prevent damage to a neutral brake in a composition which is as simple as possible.SOLUTION: Deceleration reversal gear machine 8 which is an example of a vessel propulsion device includes: a forward/backward switching mechanism 17 for switching rotational power of a main engine loaded on a vessel to forward, neutral, or reverse output; an output shaft 6 for transmitting output from the forward/backward switching mechanism 17 to a propeller 5; and a neutral brake 31 for braking an output shaft 6; as well as including a neutral brake control mechanism 61 for on one hand holding the neutral brake 31 in a braking state when the forward/backward switching mechanism 17 is in the neutral state as well being operated to brake and having the neutral brake 31 in a released state when the forward/backward switching mechanism 17 is not in the neutral state on the other hand.SELECTED DRAWING: Figure 6
【課題】中立ブレーキの損傷をできるだけ簡単な構成で防止する。【解決手段】舶用推進装置の一例である減速逆転機8は、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17と、前後進切換機構17からの出力をプロペラ5に伝達する出力軸6と、出力軸6を制動させる中立ブレーキ31とを備えるとともに、前後進切換機構17が中立状態で且つブレーキ操作されたときに中立ブレーキ31を制動状態に保持する一方、前後進切換機構17が中立状態でないときに中立ブレーキ31を解除状態にする中立ブレーキ制御機構61を備えている。【選択図】図6
