Abstract
A vehicle wheel bearing apparatus has an outer member (), an inner member (), an inner ring (), and double row rolling elements () are freely rollably retained between double row outer raceway surfaces () and double row inner raceway surfaces (). An end face at the outboard side of the inner ring () is adapted to abut a stepped portion () formed on the wheel hub (). The inner ring () is secured on the wheel hub () by being sandwiched between a caulked portion () and the stepped portion (). A ratio (α) of the thickness (e), of an end () at the outboard side of the inner ring () to abut the stepped portion (), relative to the inner diameter (d) of the inner ring () is limited at or smaller than a predetermined value.
