To provide a rolling bearing device for a wheel capable of preventing generation of worn particles, burrs and scraps when press-fitting a serrated shank portion of a hub bolt in a bolt hole of a flange.

A bolt hole 60 is formed through a flange 22 of a hub wheel 20 having a hub spindle 21 with a rolling bearing 31 assembled thereto. A serrated shank portion 73 to be press-fitted into the bolt hole 60 is formed on a root side of a shank portion 72 of a hub bolt 70 for mounting a wheel. A chamfered part 61 with the predetermined angle 1 of inclination with respect to the center axis is formed at an opening part on a press-fitting entrance side of the bolt hole 60. A chamfered part 74 with the angle 2 of inclination smaller than the angle 1 of inclination with respect to the center axis is formed at a press-fitting fore end of the serrated shank portion 73.
