A garter spring is fitted onto the outer circumferential surface of the lip seal, and the lip formed on the inner circumferential surface is compressed in the direction of pressing against the circumferential surface of the rotating shaft. A garter spring is fitted onto the outer circumferential surface of each segment seal to tighten it in the direction of pressing it against the circumferential surface of the rotating shaft, and a side ring disposed on the side is used to compress it in the axial direction. A fluid supply hole is opened that communicates with the bearing part and the packing case and supplies a sealing fluid with a higher pressure than the handling fluid to the inside of the shaft seal of the segment seal. Shaft sealing device.
