Summary:PROBLEM TO BE SOLVED: To provide a bearing device for a wheel, which prevents creep and in which sealing property is improved by adding a detent structure to the pilot member of a separate body.SOLUTION: A cylindrical fitting surface 19a is formed at the root part of a wheel mounting flange 17, and the pilot member 20 of the separated body including a cylindrical fitting part 11 which is press-fit to the fitting surface 19a is fixed. Key grooves 12a and 12b are formed in each of end parts in an engagement part 11 of the fitting surface 19a and the pilot member 20. A key 13 which becomes the dent mechanism of the pilot member 20 is locked to the key grooves 12.
