回転軸のシール装置。 An annular magnet is fixed to the outer periphery of the rotating shaft outside the bearing part, and annular magnetic pole pieces are fixed to both sides of the magnet to form a slight gap with the inner peripheral surface of the housing surrounding the rotating shaft. A magnetic circuit is formed by filling a gap between the magnetic pole piece and the inner circumferential surface of the housing with a magnetic fluid, and a side wall of the housing communicates with a magnetic fluid attached portion on an outer circumferential side of the housing and an inner circumferential side of the housing. A sealing device for a rotary shaft, characterized in that a through hole is formed and a magnetic fluid storage container for supplying magnetic fluid to the through hole is fixed to the housing.
