PROBLEM TO BE SOLVED: To prevent formation of indents in an inner ring locus or an outer ring locus during formation of a caulked part even when a cylindrical-faced outer ring is provided.SOLUTION: An uneven part 27 is formed in a circumferential direction in the bottom surface of a recessed groove 23a for locking a stop ring 24a disposed in the axial center of the outer peripheral surface of an outer ring 2c and configured to couple and fix the outer ring 2c to a knuckle 25 constituting a suspension device. When a caulked part 12a is formed, an endless belt is hung between the uneven part 27 and the output shaft of a servo motor, and the axial inner end of a hub body 9a is caulked and expanded while rotary-driving the servo motor to rotate the outer ring. |
