る直流ブラシレスフアンモータ。[Claims for Utility Model Registration] A frame, a stator supported by the frame, and a rotating shaft rotatably supported relative to the frame by a pair of bearings spaced apart in the axial direction. , a DC brushless fan motor comprising a magnet rotor with blowing blades attached to the rotating shaft, one of the pair of bearings located on the front side in the direction of air blowing by the blowing blades, and one bearing located on the front side in the direction of air blowing by the blowing blades; The other bearing located on the rear side is composed of a ball bearing and a sliding bearing, respectively, and the rotating shaft is positioned by directly or indirectly contacting the inner ring of the ball bearing at the end of the rotating shaft on the one bearing side. A retaining ring is attached to the rotor, and is set to generate a magnetic attraction force between the magnet rotor and the stator in a direction that biases the rotating shaft toward the rear side in the air blowing direction. DC brushless fan motor.
