Zusammenfassung:	PROBLEM TO BE SOLVED: To suggest a structure in which a eccentricity and variation in balance are prevented by fixing a polygon mirror and a rotor boss by the inner pressure of a spring in a polygon mirror scanner motor used for a laser scanning of a laser beam printer or a laser beam copy machine. SOLUTION: The deviation of the rotating axes of the rotor boss 2 and the mirror 3 is prevented by the expanding effect of fixing the mirror 3 by uniformly expanding the outer diameter of the rotor boss 2. Further, a gap does not exist because the rotor boss 2 is made tightly contact with the inner diameter of the mirror 3, and the variation in imbalance is reduced even when an impulsive force is applied.
