Abstract
A bearing device for a drive wheel is provided with improved strength of coupling a hub wheel and an outer joint member without significantly raising the manufacturing cost. The bearing device for a drive wheel includes the hub wheel, a constant velocity universal joint and bearings arranged in inner races, the hub wheel, the universal joint and the bearings being unitized, at least the inner race being formed in the outer joint member of the constant velocity universal joint. In the bearing device, the hub wheel and the outer joint member are meshed with each other by way of serrations and coupled to each other by caulking. Undulations of serrations at near a caulked section being filled with plastic deformed part caused by the caulking.
