PURPOSE:To reduce a noise level by 1-2dB as compared with conventional devices by suppressing the resonance of the vibration of an actuator for the focusing of a lens with a lens barrel. CONSTITUTION:A fitting plate 4 is fitted on an actuator (stepping motor) 2 through a coupling plate 3 and when the fitting plate 4 is fixed to the lens barrel 9, a vibration attenuating material 13 which is 1-2mm thickness is held therebetween. Holes into which the positioning projections 9a and screw stopping screws 14 of the lens barrel 9 penetrate are bored in the vibration attenuating material 13, and the actuator 2 is fixed to the lend barrel 9 by inserting the screws 14 into the holes. |
