    摘要: A rolling bearing (20) used in a power transmission device for transmitting power such as turning force is provided with a magnet (24) for holding in a lubrication portion of the rolling bearing a lubricating magnetic fluid (26) for lubricating the lubrication portion on at least one side of an outer race (21) of the rolling bearing, and with a L-shape annular yoke (25) made of a magnetic material loosely fitted to a rotating shaft (1) on the opposite side of said magnet relative to said outer race. The generation of mist and particulate, and pressure fluctuation and vacuum quality deterioration on a vacuum side are prevented.
