Abstract: The invention provides a brushless motor. A stator 16 of the brushless motor has a stator core 17 provided with a plurality of salient poles 18 arranged in its a circumferential direction, and a winding wire 20 wound around the plurality of salient poles 18 through an insulator 19. A rotor 22 of the brushless motor has a tubular rotor yoke 23 arranged to surround the stator 16, an annular magnet for detent torque 25 arranged in an inner peripheral portion of the winding wire 20 on the stator core 17 and surrounding the shaft 15, and a magnetic member 27 coupled to an interior surface of a ceiling portion of the rotor yoke 23 to be opposed to the magnet for detent torque 25, and surrounding the shaft 15.
