An improved ferro fluidic seal assembly having a cylindrical permanent magnet, a pair of ring-shaped yokes coupled coaxially with said magnet, and a fresh fluid storage containing ferro magnetic fluid mounted in a room defined by said magnet and yokes. Said fresh fluid storage is composed of a resilient elongated member like a stainless steel belt adapted and fixed in a circular shape along the surface of the magnet, and supplies fresh fluid to the clearance gaps defined between said yokes and a rotational body to seal said clearance gaps.
