PROBLEM TO BE SOLVED: To enable a lens main body to be hermetically sealed and to prevent the resonance of driving noise from occurring by incorporating a conventional manual module function in the lens main body and adopting such structure that the rotational force of a motor is transmitted to the lens main body by using a flexible cable. SOLUTION: The lens main body 60 is provided with a cable coupling part 62 for attaching and detaching the flexible cable 32. Besides, a gear mechanism 64 transmitting the rotational force of the cable 32 to the shaft 53 of a lens moving mechanism where a belt 48 is wound round is incorporated in the main body 60. On the other hand, the motor is incorporated in a zoom demand or a focusing demand and the rotational force of the motor is transmitted to the main body 60 through the cable 32 so that a zoom lens group or a focusing lens group is driven.
