A method and apparatus for manufacturing a legged annular member. In one aspect, a work member is formed from a ring-like raw material, and has an annular part and an outer wall part, which is formed from a leg part and a connecting part. The connecting part is removed from the work member to form an intermediate legged annular member having an annular part and a leg part. An inner diameter of the leg part of the intermediate legged annular member is expanded while a burr is removed to form a carrier, which serves as a legged annular member. Therefore, the number of manufacturing processes until completion of the carrier can be reduced, compared to performing separate processes to expand the diameter of the leg part and remove the burr. Thus, it is possible to shorten the period of time needed for completion of the carrier.
