Abstract
An amount of decrease ΔC in an axial clearance of a hub unit bearing is found based on an amount of expansion ΔD of an inner ring of the hub unit bearing, which is the difference between the outer-diameter dimension D1 of the inner ring after the inner ring is externally fitted with a tubular fitting portion of a hub spindle of the hub unit bearing and after formation of a swaged portion of the hub spindle, the inner ring being held between the swaged portion and a stepped surface of the hub spindle, and an outer-diameter dimension D0 of the inner ring before the inner ring is externally fitted with the tubular fitting portion.
