<p>A lens driving device is provided with a moving system including a lens frame to which a lens is fixed; a fixed system, including a regulating member, which regulates a guide shaft inserted into a guide hole formed on a lens frame for advancing/retracting the lens frame, and a regulating member, which regulates rotation of the lens frame about the guide shaft; a lead screw, i.e., substantially a shaft-like member, which is rotatable about the shaft to the fixed system substantially parallel to the guide shaft, and has a male screw formed thereon to be screwed together with the moving system; a motor which can advance/retract the moving system along the lead screw by rotating the lead screw about the shaft; and an urging member arranged substantially parallel to a guide shaft for urging the lens frame in the shaft direction and urging the lens frame about the shaft. Thus, in the lens driving device and the electronic device, the position of the lens frame having the lens fixed with a small number of part items can be accurately adjusted in an optical axis direction without generating deviation from the center.</p> |
