Claims

[Scope of utility model registration request]

In a rotor of a flat type motor in which a rotor case houses a rotor magnet facing a coil attached to a stator yoke, a plurality of holes are provided in the rotor case for adjusting the balance, and the holes are filled with magnetic material. A rotor for a flat type motor, characterized in that the balance of the rotor can be adjusted by inserting a weight and holding it by the attraction force of the rotor magnet.
