Disclosed is a vehicle wheel bearing device that prevents edge loading of the osculating ellipse of a ball, and that increases service life and acoustic characteristics. In the vehicle wheel bearing device, which is configured from a double-row angular ball bearing, the shoulder height of shoulders (18) of an outer member (12) is set in the range of 0.35-0.50 times the ball diameter in the double-row of balls (14); the corners (19) of the shoulders (18) are each configured from a flank (19a) that is a straight line that is tangential to an outer rolling surface (12a), and a chamfered section (19b) that is rounded in an arc having a predetermined curvature radius (r); by means of a formed grindstone that shapes the double-row of outer rolling surfaces (12a), the corners (19) are formed at that same time, and are formed smoothly and continuously from each outer rolling surface (12a); and the length (h) in the radial direction of the flank (19a) is set to be at least 0.2 mm.
