A rolling bearing device has a hub shaft having at an end a stake portion bent and deformed radially outward, a rolling bearing installed on the outer periphery of the hub shaft, and an annular member engaged by splines with the hub shaft and fixed by staking to the stake portion. An inner side end section in the axial direction of a second male spline formed in the hub shaft is positioned at a location nearer to the outer side than the inner side end section of the hub shaft in such a manner that plastic deformation of the stake portion caused by staking does not occur in the second male spline.
