PROBLEM TO BE SOLVED: To provide a zoom lens unit which is miniaturized, hardly causes eccentricity errors and tilt errors, and realizes a smooth movement of lens and a stable position adjustment. SOLUTION: A rotor 141 is rotationally driven, and a first locked part 163 and a second locked part 171 are stably guided along the first and second faces 142a and 142b of a bandlike body 142. A coil spring 145 as an energizing means energizes the leading end 1411a of the rotary shaft 1411 of the rotor 141 to the bearing 143 of the leading end with predetermined energizing force to thereby bias the leading end 1411a. Thus, accuracy in the positions of the first and second lens moving frames 16 and 17 which are to be driven, can be kept high and lens drive with high accuracy can be realized.
