船尾側シール装置。 In a ship's contra-rotating propeller, the outer shaft is equipped with the front propeller, the inner shaft is arranged concentrically within the outer shaft and the rear propeller is attached, and the stern end of the inner shaft is connected to the outer shaft. A sealable inner shaft stern side sealing device is provided, and the inner shaft has a communication hole for supplying high pressure air as a sealing fluid to the inner shaft stern side sealing device, and a communication hole for discharging a part of the high pressure air from the sealing device. A hole is formed, and the sealing device is located within a space formed by a seal liner attached to the outer circumferential surface of the inner shaft, a seal casing provided outside the seal liner, and the seal liner and seal casing. The high-pressure air supply communication hole and the discharge communication hole are each opened in a space in which the seal ring is arranged, sandwiching the seal ring therebetween. A counter-rotating propeller inner shaft stern side sealing device, characterized by:
