Abstract
A wheel hub of a wheel bearing apparatus has an outer member and an inner member. The inner member includes a wheel hub and an inner ring. The wheel hub has a wheel mounting flange, a shaft portion, an inner raceway surface, a cylindrical portion, a shoulder portion, and a through bore. The inner ring is press-fit onto the cylindrical portion abutting against the shoulder portion. Double row rolling elements are contained between the inner and outer raceway surfaces of the inner member and the outer member. Fiber flow near the inner circumference of the material forming the wheel hub from the shoulder to the open end surface of the wheel hub is in a condition substantially parallel to the axis of the wheel hub.
