<P>PROBLEM TO BE SOLVED: To mount or remove a seal member easily or to reduce the number of parts for mounting the seal member. <P>SOLUTION: In a turning bearing device 21, a sealing groove 28 is formed in a portion lower than the lower surface 23A of an outer ring 23 of the outside circumferential surface of the inner ring 22, and after an insertion part 30 of the seal member 29 is inserted into this sealing groove 28, a sealing fixing member 33 is fitted into a fitting groove 32 formed in the insertion part 30. By fitting the sealing fixing member 33 into the fitting groove 32, the fitting groove 32 is expanded, the insertion part 30 is deformed elastically and pressed to the sealing groove 28, and the seal member 29 is fixed in the sealing groove 28. The seal member 29 is attached or detached simply by attaching or detaching the sealing fixing member 33 to and from the fitting groove 32 of the seal member 29. <P>COPYRIGHT: (C)2010,JPO&INPIT |
