PROBLEM TO BE SOLVED: To prevent seizure of a friction plate in a clutch when trolling.SOLUTION: A marine gear device 8 includes: a forward/reverse selecting mechanism 16 for transmitting rotational power of an engine 7 loaded on a vessel to a propeller 5; and a trolling device 25 for adjusting hydraulic fluid pressure flowing to the forward/reverse selecting mechanism 16. Furthermore, the marine gear 8 includes: lubrication paths 42, 43 and 44 for lubricating the forward/reverse selecting mechanism 16 which are branched from a hydraulic fluid passage 24 from a hydraulic pump 21 to the forward/reverse selecting mechanism 16 through the trolling device 25; and a lubrication quantity increasing mechanism 100 for increasing lubrication oil quantity to the forward/reverse selecting mechanism 16 when the hydraulic fluid pressure flowing to the forward/reverse selecting mechanism 16 is equal to or below the trolling hydraulic pressure.SELECTED DRAWING: Figure 3

    【課題】トローリング時におけるクラッチの摩擦板の焼付きを防止する。【解決手段】マリンギヤ装置8は、船舶に搭載したエンジン7の回転動力をプロペラ5に伝達する前後進切換機構16と、前後進切換機構16に向かう作動油圧を調節するトローリング装置25を備える。また、マリンギヤ装置8は、作動油ポンプ21からトローリング装置25を介して前後進切換機構16に至る作動油路24から分岐される、前後進切換機構16への注油用の潤滑油路42,43,44と、前後進切換機構16に向かう作動油圧がトローリング油圧以下のときに、前後進切換機構16への潤滑油量を増加させる注油量増加機構100を備えている。【選択図】図3
