An inner ring member having multiple flange portions is formed by cold forging. A tapered surface is formed in a state of a forged surface on the inner ring member so as to gradually increase in diameter from an inner side toward an outer side in a vehicle lateral direction over a region from a position near root portions of inner side faces of the flange portions in the vehicle lateral direction to a position radially outward of an outer periphery of an outer end portion of an outer ring member in the vehicle lateral direction. A seal member is attached to the outer periphery of the outer end portion of the outer ring member. A seal lip that is in sliding contact with the tapered surface in the state of a forged surface is formed at a distal end portion of the seal member.
