のロータ構造。[Claim for Utility Model Registration] In 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 is rotated by a bearing of a stator of the flat motor. a rotor yoke made of a metal magnetic material that forms the base of a rotating disk around the spindle and has a supporting portion supported by the bearing on its back surface; and a surface of the rotor yoke. It is characterized by integrally comprising a resin disk member that is outsert-molded with the spindle, and a rotational drive magnet that is provided on the back surface of the rotor yoke and is attracted by the rotating magnetic field of the stator. flat motor rotor structure.
