PROBLEM TO BE SOLVED: To provide a polygon mirror scanner motor capable of improving stability.SOLUTION: A polygon mirror scanner motor comprises: a rotor 10 rotating on a rotation axis R; a plate 50 engaged with an outer peripheral surface of the rotor 10; and a polygon mirror 51 engaged with the outer peripheral surface of the rotor 10 and bonded to the plate 50. The diameter R1 of a portion engaged with the plate 50 in the rotor 10 is smaller than the diameter R2 of a portion engaged with the polygon mirror 51 in the rotor 10. |
