<P>PROBLEM TO BE SOLVED: To realize a structure capable of restricting quantity of deformation of an inner ring 3a outward in the radial direction when forming a caulking part 11. <P>SOLUTION: An inner end surface of the inner ring 3a is provided with a conical projecting surface part 18, and the conical projecting surface part 18 is pressed by the caulking part 11. When forming the caulking part 11, since the force to be applied from the caulking part 11 to the inner ring 3a outward in the radial direction can be relaxed by the force to be applied from the caulking part 11 to the conical projecting part 18 inward in the radial direction, the described problem can be solved. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
