Zusammenfassung:PROBLEM TO BE SOLVED: To prevent a situation that a lens barrel resonates with the driving of a lens driving motor to amplify noise without changing external shape by forming a recessed part at a part covered with a motor frame, arranging a vibration-proof member in a recessed part and crashing the vibration-proof member in the case of fixing the motor frame. SOLUTION: The principal part 5 of the motor frame 4 is placed on the pedestal part 10 of the lens barrel 7 from above through the vibration-proof member 14, and screws 20 and 20 pierce the principal part 5 of the motor frame 4 and are screwed in the screw hole 12a and 12a of washer parts 12 and 12, so that the motor frame 4 supporting a lens driving motor 1 is attached to the lens barrel 7. In such a case, the member 14 is crashed by the motor frame 4 and the recessed part 11 of the lens barrel 7. Since the motor frame 4 is attached to the lens barrel 7 through the member 14 arranged in the recessed part 11, the crashed member 14 functions as a cushioning material so as to prevent the situation that the lens barrel 7 resonates with the driving of the motor 1 to amplify the noise.
