PROBLEM TO BE SOLVED: To improve the response of a vehicle attitude control system to a change in the state of a road surface by installing a means for acquiring information appropriate for controlling the attitude of a vehicle in a bearing device itself and accurately and safely control the attitude of the vehicle in the bearing device for drive wheel formed by unitizing a hub wheel, a constant velocity universal joint, and a bearing to each other. SOLUTION: In this bearing device for the drive wheel, the hub wheel 10, the constant velocity universal joint 40, and the bearing 20 are unitized to each other. The hub wheel 10 is fitted to the outer periphery of the stem part 45 of the outer joint member 41 of the constant velocity universal joint 40. An inner member 29 is formed of the outer joint member 41 and the hub wheel 10. One raceway surface 27 of the double-row inner peripheral raceway surfaces 27, 28 of the bearing 20 is formed on the hub wheel 10, and the other raceways surface 28 is formed on the outer joint member 41.
