PROBLEM TO BE SOLVED: To provide a thin brushless motor with a rotor stopper function to be assembled in a simple structure. SOLUTION: The brushless motor includes a rotor case 11, a shaft 12 fixed to the rotor case 11, a rotor 10 having a magnet 13 fixed to the inner circumferential surface of the rotor case 11, a radial bearing 23a rotatably supporting the shaft 12, a bearing holder 24 holding the radial bearing 23a, a stator core 27 wound with a coil 26 disposed opposed to the magnet 13, and a stator 20 having a stator base 21 provided with a printed circuit board 22 connected to the terminal of the coil 26. The shaft 12 has a locked part above the radial bearing 23a, and a slipping-out preventive member of a wire spring which abuts on the locked part when the rotor 10 axially moves.
