置。In a device that axially seals oil on one side of the shaft and air on the other side by bringing the inner lip of the seal ring into contact with the outer circumference of the rotating shaft, the back surface of the seal ring on the air side is made of a magnetic material. An elastically deformable metal ring is attached, and the seal ring is fitted onto the rotating shaft side made of a magnetic material, and the cooperation between the metal ring and the rotating shaft side generates a magnetic field on the back side near the inner circumferential lip. What is claimed is: 1. A sealing device for a rotating shaft, characterized in that a magnetic field is formed and a magnetic fluid is sealed in the magnetic field.
