摘要：
A wheel bearing apparatus has an outer member, an inner member and double row rolling elements freely rollably contained between double row inner raceway surfaces and outer raceway surfaces of the inner member and the outer member. A plurality of bolt insertion bores, that fastening bolts pass through to fasten to the knuckle, are formed on the body mounting flange at plurality of positions circumferentially along the body mounting flange. The outer member is previously formed by hot forging. A seating surface for the fastening bolts is formed on an outboard-side surface of the body mounting flange by cold forging.
