Abstract:
One object is to provide a magnetic fluid sealing device in which a magnetic fluid retained between a polar plate and a drive portion can be effectively prevented from spilling, so as to retain waterproofness for a long period. A magnetic fluid sealing device of the present invention includes a ring-shaped polar plate encircling a drive portion and retaining a magnet and a magnetic fluid retained in a gap between the drive portion and the polar plate by a magnetic force of the magnet. The polar plate has a spill preventing portion provided thereon, the spill preventing portion having a projecting wall that is disposed distant from an end surface of the polar plate retaining the magnetic fluid, so as to prevent spill of the magnetic fluid.

Claim (Index 6):
A method of producing a polar plate having a resin film attached thereto,\n wherein the spill preventing portion of  claim 1  is made of a resin film attached to an exposed surface of the polar plate such that the projecting wall is distant from the end surface of the polar plate so as to be flush with the end surface of the polar plate, and wherein the method of producing the polar plate having the resin film attached thereto comprises the steps of: forming a stacked sheet having lamination structure including a sheet-shaped magnetic member and a sheet-shaped resin sheet stacked on and adhered to a surface of the magnetic member; and punching the stacked sheet to produce a plurality of ring-shaped polar plates having a resin film attached thereto.
