The present invention relates to a boss cap having an asymmetric fin and a propulsion apparatus for a ship having the same. The boss cap having an asymmetric fin comprises: a cap which is coupled to a boss rotated by the driving force generated by a driver; and a fin which is coupled to the cap to protrude from the cap, wherein the fin is formed in an asymmetric shape protruding in a first direction to correspond to an asymmetric propeller protruding in the first direction. Therefore, the present invention reduces driving force loss by dispersing a swirl generated in the rear of the boss.

    본 발명은 구동부가 발생시킨 구동력에 의해 회전되는 보스에 결합되는 캡, 및 상기 캡으로부터 돌출되게 상기 캡에 결합되는 핀을 포함하되, 상기 핀이 제1방향으로 더 돌출된 비대칭형으로 형성된 프로펠러에 대응되도록 상기 제1방향으로 더 돌출된 비대칭형으로 형성되는 것을 특징으로 하는 비대칭형 핀을 갖는 보스캡 및 이를 포함하는 선박용 추진장치에 관한 것이다.
