<p>An outer ring (45) and rolling elements (50) are fitted to a shaft portion (10) of a shaft member for a wheel rolling bearing device from a shaft end portion (15) of the shaft member, an inner ring (42) and rolling elements (51) are fitted to the shaft portion, and then the shaft end portion (15) is clinched (P) to form a clinched portion (17) to thereby fix the inner ring. At this time, the shaft end portion (15) to be clinched has a solid columnar shape, and a clinching jig (P) is pressed against the shaft end portion (15), and the clinching jig (P) is oscillated while being pressed in a direction toward one end side of the shaft portion to thereby increase the diameter and clinch the shaft end portion.</p> |
