PROBLEM TO BE SOLVED: To provide a rolling bearing unit with a rotary member for brake with a low manufacturing cost and having excellent performances in reducing vibration and noise generated during braking without complicating assembly work at an automobile assembly plant. SOLUTION: A stud supported on a mounting flange 13 is loosely inserted into an insertion hole 24 to support a rotor 2 on the outer surface of the mounting flange 13. Under this condition, the tip part of a coil spring 28 is locked with a male screw 29 of the stud 9 and the base end part thereof is elastically abutted on the periphery of the insertion hole 24 at a part of the outer surface of the rotor 2. By this constitution, the rotor 2 is completely connected to the mounting flange 13 to form a rolling bearing unit with a rotary member for brake.
