Disclosed is a stern tube sealing device including an antistatic structure. In accordance with an embodiment of the present invention, the stern tube sealing device, which is mounted at one end of a stern tube attached to the circumference of a shaft of a vessel to form a shaft rotation space therein, includes: a sealing body part formed in a structure inserted by a predetermined depth from one end of the stern tube to be mounted, and extended from the one end of the stern tube by a predetermined length to surround the circumference of the shaft; a static electricity absorption member mounted at one end of the sealing body part, mounted in contact with a part of the outer circumference surface of the shaft, and made of a carbon material; an absorption member mounting part mounted at one end of the sealing body part, fixing a position of the static electricity absorption member in a structure surrounding a part of the outer surface of the static electricity absorption member, and having an elastic member embedded therein to press the static electricity absorption member in a direction vertical to the outer circumference surface of the shaft; and a static electricity ground line mounted on one side of the absorption member mounting part, and removing the static electricity absorbed by the static electricity absorption member to the outside. In accordance with the present invention, since the stern tube sealing device is mounted at the one end of the stern tube in which the propeller shaft of the vessel is mounted to prevent the generation of static electricity in the stern tube, the stern tube sealing device can fundamentally prevent damage to the propeller shaft caused by the static electricity.

    정전기 방지구조를 포함하는 선미관 씰링장치가 개시된다. 본 발명의 실시예에 따른 선미관 씰링장치는, 선박의 샤프트 둘레에 밀착되어 내부에 샤프트 회전공간을 형성하는 선미관의 일단부에 장착되는 선미관 씰링장치로서, 상기 선미관의 일단부로부터 소정 깊이만큼 삽입되어 장착되고, 선미관 일단부로부터 소정 길이만큼 연장되어 샤프트 둘레를 감싸는 구조로 형성된 씰링본체부; 상기 씰링본체부의 일단에 장착되고, 샤프트의 외주면 일부와 접촉하도록 장착되며, 카본소재로 구성된 정전기 흡수부재; 상기 씰링본체부의 일단에 장착되고, 정전기 흡수부재의 외부면 일부를 감싸는 구조로 정전기 흡수부재의 위치를 고정하고, 정전기 흡수부재를 샤프트의 외주면과 수직한 방향으로 가압하는 탄성부재가 내장된 흡수부재 장착부; 및 상기 흡수부재 장착부의 일측면에 장착되고, 정전기 흡수부재로부터 흡수된 정전기를 외부로 소멸시키는 정전기 접지라인;을 포함하는 것을 구성의 요지로 한다. 본 발명에 따르면, 선박의 프로펠러 샤프트가 장착되는 선미관의 일단부에 장착되어 선미관 내부에 정전기가 발생되는 것을 방지함으로써 정전기에 의한 프로펠러 샤프트의 손상을 원천적으로 차단할 수 있는 선미관 씰링장치를 제공할 수 있다.
