To provide a roller bearing device for a wheel that can prevent an inclination of a center axis of a hub bolt shaft by its simple structure.

A flange 22 of a hub wheel 20 has a bolt hole 60 into which a shaft part 71 of a hub bolt 70 is press fitted. An opening part of a press fitting inlet of the bolt hole 60 has a countersunk part 61 having a tapered opening 62. A head part 71 of the hub bolt 70 has a chamfering part 72 fitted in taper to the tapered opening 62 of the countersunk part 61. When the shaft part 71 of the hub bolt 70 is press fitted into the bolt hole 60 in a flange 22, the chamfering part 72 at the head part 71 of the hub bolt 70 is abutted against the tapered opening 62 of the countersunk part 61 and fitted in taper, so that a center axis of a shaft part 73 of the hub bolt 70 and a center line of the bolt hole 60 are concentrically positioned to each other by this fitting action.
