<P>PROBLEM TO BE SOLVED: To provide a sealing structure which can easily fix a sealing device to a first member and make the sealing device hard to extract from the first member, and bearing unit having such a sealing structure. <P>SOLUTION: A part of radially extending section 70 located at a radial outside of axial end surface fixing section 46 fixed to a radial end surface of cylindrical section 51 of core bar member 41 is expanded to a radially outward side by a reaction force from an axially inner side surface 17 of a first sealing device attaching groove 14. Furthermore, a first sealing device 4 is fixed to the first sealing device attaching groove 14 by firmly fastening the first sealing device 4 to the first sealing device attaching groove 14 by screw engagement so that the part of this radially extending section 70 may be sandwiched between a female thread section 48 of the first sealing device attaching groove 14 and male thread section 47 of the core bar member 51. <P>COPYRIGHT: (C)2010,JPO&INPIT |
