<P>PROBLEM TO BE SOLVED: To provide a lens barrel which can be made thin in an optical axis direction and small in a radial direction. <P>SOLUTION: In the optical axis direction, a first driving part X and a second driving part Y are arranged to be partially superposed on a small-diameter lens 22. In the radial direction, the first driving part X and the second driving part Y are arranged partially out of projection area of the small-diameter lens 22 and within projection area of a large-diameter lens 20 when projecting a first lens group (large-diameter lens 20 and small-diameter lens 22) and the first driving part X and the second driving part Y in a plane. <P>COPYRIGHT: (C)2009,JPO&INPIT |
