본 발명은 선박용 격납식 추진기 조립체(10)의 추진기지지관(20)에 쓰이는 밀봉 구조체(19)에 관한 것이다. 가동 추진기지지관(20)과 개구부(50)를 가지는 토대판(22) 사이를 밀봉하는 해당 밀봉 구조체(19)는 공기주입상태에서 개구부(50)와 추진기지지관(10) 사이를 밀봉하는 공기주입식 밀봉 링(106)을 포함해도 좋다. 이 경우 공기주입식 밀봉 링(106)은 수리용 씰 및 긴급용 씰 양쪽 모두로 기능할 수 있다.

    The present disclosure relates to a sealing assembly (19) for a thruster support pipe (20) of a retractable thruster assembly (10) of a marine ship or vessel. The sealing assembly (19) for sealing between the movable thruster support pipe (20) and a foundation plate (22) with an opening (50) may comprise a main body (80) with a first inner sealing ring (90), a bearing (84), and an outer sealing ring (104). The main body (80) may be allowed to radial move with the thruster support pipe (20) within the opening (50). Thus, excessive radial forces particularly on the sealing assembly (19) may be reduced.
