PROBLEM TO BE SOLVED: To provide a rolling bearing device suitable for preventing erroneous detection of a rotation sensor when a moment load is applied. SOLUTION: A thin motor 100 is provided with a deep groove ball bearing 14 having an inner ring 14a and an outer ring 14b, a stator 22 supported by the inner ring 14a, a rotor 12 supported by the outer ring 14b, a motor part 16 imparting rotation torque to the rotor 12, and a resolver 30 for detecting a rotation angle position of the rotor 12. The resolver 30, the deep groove ball bearing 14 and the motor part 16 are arranged on a radial same plane. An electromagnet 50 fixed to the stator 22 and a permanent magnet 48 fixed to the rotor 12 are provided, and the electromagnet 50 and the permanent magnet 48 are arranged to confront with each other in the axial direction while having a prescribed gap.
