Abstract
A bearing device for a driving wheel includes an outer race having an inner periphery in which double-row outer raceway surfaces are formed; a hub wheel and an inner race having outer peripheries in which double-row inner raceway surfaces opposed to the outer raceway surfaces are formed; and double-row rolling elements interposed between the outer raceway surfaces and the inner raceway surfaces. A shaft hole of the hub wheel is formed into a cylindrical shape, and a male spline is formed on an outer periphery of a stem section of the outer joint member so that the stem section of the outer joint member is press-fit into the shaft hole of the hub wheel. With this, recesses caused to fit on the male spline with interference are formed in the shaft hole of the hub wheel, whereby the hub wheel and the outer joint member are separably coupled to each other.
