の扁平モータのロータ構造。[Scope of Claim for Utility Model Registration] A rotor structure of a flat motor of a disk device using a recording medium formed by rotatably housing a magnetic sheet fixed to a rotating hub made of a magnetic material, the rotor being made of a metal magnetic material. A yoke, a spindle rotatably supported by a bearing of a stator of a flat motor, and a rotating disk made of resin that supports the rotor yoke with respect to the spindle and rotates integrally with respect to the spindle. A rotor structure for a flat motor for a disk device, characterized in that a first magnetized part that attracts a hub and a second magnetized part that is attracted by a rotating magnetic field of a stator coil are integrally molded.
