PROBLEM TO BE SOLVED: To improve the downsizing of a motor unit and the reliability of operation by ensuring tightening force (press fitting force) for a motor shaft. SOLUTION: This motor unit comprises a rotor 24 which has a rotor case 36 and a magnet 37 fixed on the rotor case, a stator 23 which has a plurality of stator coils 29, 29,... disposed so as to face the magnet of the rotor, a motor shaft 25 rotated together with the rotor, a yoke 40 which is formed out of an iron series sintered material and fixed on the motor shaft by press fitting, and a disc table 22 which is formed out of a resin material and fixed so as to be fitted onto the yoke. |
