PROBLEM TO BE SOLVED: To provide a DC brushless motor exhibiting full rotor attraction performance with a small number of components while attaining silence. SOLUTION: An auxiliary magnet 19, subjected to unipolar polarization in the axial direction, is provided on the outer circumference of a stator housing 8, and a rotor shaft 6 is supported, while abutting against a thrust pad 18 inside the stator housing 8 produced by magnetic attraction between a rotor yoke 3 that faces the auxiliary magnet 19.
