転支持装置。 A fixed shaft with a shaft sleeve provided on the outer periphery and a polygonal rotating body with a mirror surface formed on the outer circumferential surface are provided, and the rotating body is supported by the fixed shaft and upper and lower thrust plates, and is used for generating torque. In the rotation support device for a polygon mirror, the magnet is integrally provided with the rotating body, and the rotating body includes a ceramic rotor rotatably provided on the outer periphery of the shaft sleeve, and a ceramic rotor arranged on the outer periphery of the ceramic rotor. The rotor includes an aluminum rotor whose radially outer peripheral surface is machined with the mirror surface, and a yoke to which the ring-shaped magnet is bonded and shrink-fitted to the outer periphery of the ceramic rotor. The aluminum rotor and the yoke are connected by holding bolts,
A rotation support device for a polygon mirror, characterized in that it is integrally fixed by a holding ring and an elastic plate.
