流体シール装置。 a rotating member rotatably supported within a housing; magnetic poles arranged to divide the housing in the axial direction by forming a minute gap between the rotating member; and axially opposing side surfaces; It has an outer circumferential surface that is inscribed in the housing and an inner circumferential surface that faces the rotating member, and one side of the axially opposing sides is in contact with the magnetic pole so that a magnetic circuit is formed by the combination of the rotating member and the magnetic pole. A magnetic fluid sealing device comprising a magnetic force source arranged and a magnetic fluid filled in a minute gap between the rotating member and the magnetic pole, the inner periphery of the one side surface adjacent to the magnetic pole of the magnetic force source. An annular groove for accommodating the magnetic fluid is formed on the surface side before assembling the magnetic pole and the magnetic source into the housing, and one side surface and the inner peripheral surface are respectively magnetized to different magnetic poles. Features of magnetic fluid seal device.
