<P>PROBLEM TO BE SOLVED: To provide an anti-friction bearing fitment which realizes space saving and plans to reduce a built-in man power of detecting mechanism. <P>SOLUTION: In the anti-friction bearing fitment, used for a compressor fitment of fuel cell, comprising a pair of anti-friction bearing fitments 4 which bear a rotary shaft 3 to which parts of compressor or the like are fixed, the anti-friction bearing 4 comprises an outer ring of spiral wound gasket 12 in which an outside rolling face 12a is formed in inner periphery, an inner ring of spiral wound gasket 13 in which an inside rolling face 13a is formed in outer periphery, and a plurality of ball 15 accommodated between both rolling faces through retainer 14 in such a manner of freely rolling, and a sensor holder 23, formed in one end of the outer ring of spiral wound gasket 12 in a circle with sheet steel, is attached, furthermore, a detector 26 consisting of synthetic resin is integrally molded to this sensor holder 23, then a sensor 27 is embedded in this detector 26, and a rotating speed of the compressor is made to be detected by attaching a rotary element 22 consisting of a magnetic encoder facing this sensor 27 to the inner ring of spiral wound gasket 13 simultaneously. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
