<P>PROBLEM TO BE SOLVED: To provide a sealing device of a rolling bearing, which is integrated with a magnetizing member for detection of rotation, prevents damages on a lip of a sealing device to be stacked and does not degrade the sealing performance. <P>SOLUTION: A sealing device 1 of a rolling bearing includes a core metal 2, a slinger 3, a seal member 4 and a pulser ring 5. The seal member 4 includes a disk inner seal part 42 mounted on an inner surface of a disk core metal part 22, a disk outer seal part 45 mounted on an outer surface of the disk core metal part 22, an axial lip 43a extending from the disk inner seal part 42 and sliding on an inner surface of a disk slinger part 32, and a projection part 42a protruding from the disk outer seal part 45 and formed continuously or intermittently in a circumferential direction. The seal member 4 has an extended part 44 extending from the disk inner seal part 42 to near the opposing disk slinger part 32; and the diameter of the annular projection part 42a centering the shaft center is approximately equal to the diameter of the extended part 44. <P>COPYRIGHT: (C)2013,JPO&INPIT |
