体シール装置。[Claims for Utility Model Registration] Two annular pole blocks surrounding a magnetic cylinder mounted on a rotating shaft are mounted on the inside of a cylindrical bearing housing so as to face each other with a distance between them. A magnet is bridged between the annular pole blocks 1, a plurality of annular microprotrusions are provided on either the inner peripheral surface of the pair of annular pole blocks or the magnetic cylinder, and the annular microprotrusions are provided between the annular microprotrusions and the opposing surface. A magnetic fluid supply pipe is provided that penetrates the bearing housing and the annular pole block in order to interpose the magnetic fluid in the bearing housing, and the sound is applied to the space near the magnetic fluid interposed between the annular microprotrusion and the surface facing the same. A sensor is installed to detect changes in sound in this space, and this is sent to a judgment device to make a judgment. If the above-mentioned magnetic fluid scatters, it will automatically send a predetermined amount of magnetic fluid to the replenisher. 1. A magnetic fluid seal device characterized in that:
