Abstract
A hub wheel () and an outer joint member () are coupled to each other through intermediation of a recess-projection fitting structure (M). The recess-projection fitting structure (M) can be separated by being applied with a pulling-out force in an axial direction under a state in which a bolt member () is removed, and can be re-formed by re-screwing the bolt member () into a bolt hole (). The hub wheel () comprises a receiving portion () for receiving the bolt member (). The shaft portion () has a small diameter portion () serving as a fit-in portion to be fitted along an inner periphery of the receiving portion () under a state in which the recess-projection fitting structure (M) is formed. The small diameter portion () is used as a part for confirming the accuracy and the state of the recess-projection fitting structure (M).
