PROBLEM TO BE SOLVED: To provide a rolling bearing device capable of suppressing noises emitted from the wheels when a vehicle runs in cornering. SOLUTION: The circumferential direction width B1 of a thick wall part 30 of a hub flange 12 is formed as large as the circumferential direction width B2 of a seat face 32 to a brake disc 14 of a thick wall part 37 of each wheel 15. By this constitution, the noises generated from the wheels during steep cornering can be effectively suppressed for a long period of time. COPYRIGHT: (C)2005,JPO&NCIPI
