摘要： PROBLEM TO BE SOLVED: To manufacture an inner ring or an outer ring with large diameter flange part at a low cost.
SOLUTION: Among the inner ring and the outer ring, at least one (hub shaft 31) is formed in a two piece structure comprising a body 33 and the flange part 34. The flange part 34 comprises, for example, a wheel. The flange part 34 is formed in a ring shape by bending a band-like sheet metal around an axis orthogonal to a plane including the plate surface thereof and both end parts thereof are connected to each other. When the inner ring or the outer ring having the flange part 34 is manufactured, only the body 33 of the inner ring formed in a small diameter may be forged by a rather small-sized forging machine and facility.
