Provided is a bearing device for a wheel, including a bearing (20) for a wheel including: an outer race (5) having double-row outer raceway surfaces (13, 14) formed on an inner circumference thereof; a hub wheel (1) and an inner race (2) having double-row inner raceway surfaces (7, 8) formed on an outer circumference thereof so as to be opposed to the outer raceway surfaces (13, 14); and double-row rolling elements (3, 4) interposed between the outer raceway surfaces (13, 14) of the outer race (5) and the inner raceway surfaces (7, 8) of the hub wheel (1) and the inner race (2), the bearing (20) for a wheel having a constant velocity universal joint (6) coupled thereto with a screw fastening structure (M) by fitting a stem section (30) of an outer joint member (24) to a shaft hole of the hub wheel (1), in which the shaft hole (38) of the hub wheel (1) is formed by penetrating the hub wheel (1) into a cylindrical shape over an axial direction of the hub wheel (1), in which the hub wheel (1) includes a plurality of concave portions (39) formed on the shaft hole (38) thereof by broaching so as to have interferences with convex portions (37) of the stem section (30) of the outer joint member (24), respectively, and in which the stem section (30) of the outer joint member (24) is press-fitted to the shaft hole of the hub wheel (1), and a shape of each of the convex portions (37) is transferred to the shaft hole, to thereby define a convex and concave fitting structure in which the convex portions (37) and the concave portions (39) are brought into close contact with each other at an entire fitting contact portion therebetween.
