Abstract
A drive wheel bearing device is provided with an outer member, an inner member, double-row rolling elements and a constant velocity joint. The inner member includes double-row inner races opposite outer races of the outer member, a first inner member, and a second inner member formed with at least one of the double-row inner races, the first inner member and the second inner member being inseparably coupled together at a flange-like swaged portion. The constant velocity joint includes an outer joint member press-fitted to an inner periphery of the first inner member with torque transmission means formed therebetween that transmits torque by engagement of a plurality of axially extending teeth, wherein the torque transmitting teeth of the first inner member have a tooth profile that is controlled within a specified range over the entire axial length of the teeth.
