PROBLEM TO BE SOLVED: To provide a lens frame for moving a plurality of optical elements forward and backward as one body. SOLUTION: Provided is the lens frame 18 for the optical element group which is moved forward and backward along the optical axis by the driving force of a driving means 37 to vary the magnification of an observed image. One optical element 14 in the optical element group, a holding frame body 22 holding the optical element group, and a coupling member 23 which couples the holding frame with the driving means are formed of a single material in one body. The holding frame body 22 has a holding part 39 formed to integrally hold at least other one optical element 15 in the optical element group. COPYRIGHT: (C)2004,JPO
