PROBLEM TO BE SOLVED: To provide the bearing device for a wheel which can arrange two ball rows on the same shaft and impart a proper preload easily, while omitting a prescise processing. SOLUTION: In the bearing device for a wheel having a constant velocity joint outer ring 12 with a first ball rolling surface 12b and a hub 14 having a second ball rolling surface 14b and connected to a driving wheel, in which the end 14a of the hub is connected to the end 12a of the constant velocity joint outer ring and the rotary member 10 is formed and in which a bearing outer ring 18 is supported through the ball rows 16a, 16b arranged on the first/ second ball rolling surfaces of this rotary member 10, the end of the constant velocity joint outer ring is connected to the end of the hub by a friction press- contact.
