ペラシヤフトの摺動部のシール装置。[Claims for Utility Model Registration] (1) A spline shaft is slidably engaged in the sliding yoke of the propeller shaft, and the sliding yoke has a grease nipple for injecting grease into the sliding part of the propeller shaft. In a sealing device for a propeller shaft sliding part, in which a sealing member is provided between an end portion and the spline shaft, the spline of the spline shaft is provided near the sealing member and passing through a wall of the sliding yoke. 1. A sealing device for a sliding part of a propeller shaft, comprising: a breather opening in the sliding part of the propeller shaft; and a grease passage for returning grease escaped into the breather to the grease nipple. (2) The breather comprises a ball valve that closes a through hole penetrating the wall of the sliding yoke, and a spring that normally biases the ball valve to close. The sealing device for the sliding part of the propeller shaft described above.
