Abstract:
A wheel bearing apparatus incorporating an in-wheel motor has a connecting shaft. The connecting shaft has a disc portion, forming the planetary elements, and a shaft portion, axially extending from the disc portion, via a shoulder portion. The outer circumference of the shaft portion has a serration. The connecting shaft is inserted into the wheel hub until the disc portion abuts the inner member. A seal ring, formed of elastic material, is interposed between the inner member and the connecting shaft to shield the driving portion from the outside in a liquid-tight manner.
