PROBLEM TO BE SOLVED: To provide a stern tube seal device in which a liner can be mounted to a propeller shaft easily and which comprises seal rings capable of withstanding for a long life, and provide a ship equipped with the same.SOLUTION: A stern tube seal device 1 comprises: a liner 19 which is externally fitted to a propeller shaft connected to a propeller that is mounted to a stern of a ship; and a plurality of seal rings 11 arranged at different shaft-direction positions in a shaft direction of the propeller shaft so as to slide-contact with the outer peripheral surface of the liner. The liner includes: a heat conduction part 19a5 in contact with the outer peripheral surface of the propeller shaft at least in the shaft-direction position of each seal ring; and a gap formation part 19a2 for forming a gap between the outer peripheral surface of the propeller shaft and the liner, which is provided at least in one part of a region other than the heat conduction part in the shaft direction.
【課題】ライナーのプロペラ軸への装着作業が容易であり、長寿命に耐えうるシールリングを備えた船尾管シール装置、及びこれを備える船舶を提供する。【解決手段】船尾管シール装置1は、船舶の船尾に装着されるプロペラに連結されるプロペラ軸に外嵌されるライナー19と、前記ライナーの外周面に摺接するように、前記プロペラ軸の軸方向において互いに異なる軸方向位置に配置される複数のシールリング11と、を備え、前記ライナーは、少なくとも、各々の前記シールリングの前記軸方向位置において前記プロペラ軸の外周面に接触する熱伝導部19a5と、前記軸方向における前記熱伝導部以外の領域の少なくとも一部に設けられ、前記プロペラ軸の外周面と前記ライナーとの間に空隙を形成するための空隙形成部19a2と、を含む。【選択図】図3
