<P>PROBLEM TO BE SOLVED: To provide a structure that is practical, that hardly causes a failure due to squeezing-out of adhesive or the like during manufacture, and that can sufficiently secure sealability of a coupling part of a cylindrical part 15a constructing a slinger 13a and an outer peripheral surface of an inner ring 21 for a long period. <P>SOLUTION: A sealing deformation part 24 formed by heating and deforming an inner peripheral part of an encoder 20b made of a plastic magnet is brought into close contact with an outer peripheral surface of an inner ring 21 over an entire periphery thereof. Then, the sealing deformation part 24 seals an opening part of a gap existing between a curve surface part 17a of a slinger 13a and the outer peripheral surface of the inner ring 21, over an entire periphery thereof. <P>COPYRIGHT: (C)2013,JPO&INPIT |
