摘要： 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.

摘要： Crowing is applied to a side surface of an inner ring which abuts against a side surface of a drive shaft in a radial direction. With this construction, when the two side surfaces abut against each other by a pressing operation of a threadedly-engaged nut at the time of connecting the drive shaft and an inner shaft, a contact pressure distribution of abutting surfaces is made generally uniform, thereby suppressing the occurrence of an edge load. By thus preventing a contact pressure from increasing at part of the abutting surfaces, energy released by a stick-slip phenomenon is reduced, and a sound pressure level of an abnormal sound generated at this time is reduced.
