To provide a ship propeller capable of driving a propeller shaft by either one or both of an engine and an electric motor, while enabling coupling even in a state that there is a little rotational difference between input and output of a clutch.SOLUTION: A ship propeller includes: a forward gear 15 and a backward gear 16 engaged with a pinion gear 14 at an engine 2 side; clutches 17, 18 disposed between each of the gears 15, 16 and a propeller shaft 11; and a path for transmitting power of an electric motor 4 to the propeller shaft 11 by a path independent from both clutches 17, 18. The clutches 17, 18 retain an engagement element 40 positioned between an external portion 20 integrated with the gear 15 or 16 and an internal portion 30 integrated with the propeller shaft 11, by a retainer 50, move the engagement element 40 from a neutral position to an engagement position by relatively rotating the retainer 50 to the external portion 20 by magnetically attracting an armature 70 locked to the retainer 50 to a rotor 90 by an electromagnet 80. A neutral spring 60 and a separating spring 100 are disposed for returning of the engagement element 40 and the like.SELECTED DRAWING: Figure 1

    【課題】クラッチの入出力間で多少の回転差がある状態でも結合を行うことが可能でありながら、エンジンと電動モータの一方でも両方でもプロペラシャフトを駆動可能な船舶推進機にする。【解決手段】エンジン2側のピニオンギヤ14と噛み合う前進ギヤ15及び後進ギヤ16と、ギヤ15、16の夫々とプロペラシャフト11間に設けたクラッチ17、18と、電動モータ4の動力を両クラッチ17、18から独立した経路でプロペラシャフト11に伝達する経路とを備える。クラッチ17、18は、ギヤ15又は16と一体的な外方部20と、プロペラシャフト11と一体的な内方部30との間に位置する係合子40を保持器50で保持し、保持器50に対して回り止めされたアーマチュア70を電磁石80でロータ90に磁気吸着させることで保持器50を外方部20に対し相対回転させて係合子40を中立位置から係合位置に移動させ、係合子40等の復帰用に中立ばね60、離反ばね100を設ける。【選択図】図1
