Abstract
A caulked portion is formed by plastic deformation of a cylindrical portion which is formed at the inner end of a shaft member and is reduced in thickness toward the leading end in a diametrical outward direction. The force required to form the caulked portion is reduced, and the caulked portion is less susceptible to damage. Further, the force of the caulked portion for supporting the inner ring is ensured.
