SOLUTION: The bearing device for the wheel consists of a hub 1 and the bearing 2 for the wheel. The bearing 2 for the wheel has two inner rings 3A, 3B respectively press-fit to an outer circumference of a shaft part 1a of the hub 1 side by side and an outer ring 4. Between the inner wheels 3A at the out board side and the hub 1, a rotation stop member such as a key 20 for stopping relative rotation of both of them is provided and the key 20 fits along between key grooves 21, 22 provided in an outside surface of the shaft part 1a of the hub 1 and an inside surface of the inner ring 3A.
