Abstract
A vehicle hub unit includes: an outer ring; rolling elements; a hub wheel that is arranged radially inward of the outer ring via the rolling elements; and an inner ring member that is fixed to an end portion of a hub spindle of the hub wheel by clinching. A spline tooth portion that meshes with a tooth portion of a constant velocity joint that transmits driving force to the hub unit is formed at a clinched portion of the hub spindle. A protruding portion is formed at a radially inner side portion of a bottom of the spline tooth portion.
