Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a polygon mirror rotary driving device capable of preventing surfaces of a polygon mirror from tilting and a jitter value from becoming worse even when the polygon mirror is rotated at a high speed. SOLUTION: In the polygon mirror rotary driving device 1 comprising the polygon mirror 2, a stator 20 which has a stator core 22 wound with a driving coil 21 and a fixed shaft 24, and a rotor 10 which has an insertion hole 11 where the fixed shaft 24 is inserted, a rotor magnet 12 opposed to the stator core 22, and a mirror mount part 16 where the polygon mirror 2 is mounted, a gap part 8 is formed between an outer peripheral surface of the fixed shaft 24 and an inner peripheral surface of the insertion hole 11 and the rotor 10 is hermetically sealed to prevent air flowing in and out through the gap part 8.
