PROBLEM TO BE SOLVED: To adopt structure with excellent detaching/attaching property of a brake disc, in a rolling bearing device having the brake disc. SOLUTION: The brake disc 4 is assembled from a vehicle outer side of the rolling bearing device 1 so that the brake disc is mounted while the brake disc is disposed to a face of a vehicle inner side of a flange 21 of a hub wheel 2, and the brake disc 4 can be detached from a direction opposite to a direction of the assembly. Therefore, even when the brake disc 4 is attached/detached after the rolling bearing device 1 is mounted to a vehicle body, since only the brake disc 4 can be separately detached without detaching the rolling bearing device 1 from the vehicle body, maintenance property is improved.
