PURPOSE:To provide a motor, in which rotary balance can be kept for a prolonged term by inhibiting the generation of backlash in a device and which can be used for the prolonged term as compared to conventional devices by enabling second adjustment when rotary balance is lost. CONSTITUTION:The diameter of the revolution of a magnet yoke 13 is formed in size larger than a part of the outside diameter of a stator section, and a balance adjusting member 16 is mounted inside the magnet yoke 13. Since the balance adjusting member 16 is installed, the backlash of the member due to the vibrations of a motor is eliminated, thus employing the device for a prolonged term. The balance adjusting member 16 can be exchanged and mounted and dismantled without disassembling the device, thus easily adjusting balance again. |
