Abstract
A polygon scanner motor has a polygon mirror having an outer periphery, a mirror surface for scanning light arranged around the outer periphery, and a setting hole having an inner periphery. A rotor has a projection having a plastically deformable edge portion. The polygon mirror is positioned relative to the rotor so that the edge portion of the projection is disposed opposite a surface portion of the inner periphery of the setting hole proximate a center of the inner periphery in the axial direction thereof. The edge portion of the projection is plastically deformed against the surface portion of the inner periphery of the setting hole to thereby connect the polygon mirror to the rotor.
