Abstract

PURPOSE:To move two zoom lens holding members smoothly, by fitting tongue- shaped parts provided in two zoom lens holding members to notch parts facing to each other. CONSTITUTION:An outside circumferential face 38 of the first zoom lens holding member 36 holding first zoom lenses 30, 32, and 34 is engaged with a guide part 40 on the inside circumferential face of a barrel 26, and in respect to the movement in the direction of the optical axis, the first zoom lens holding member 36 is slided and guided by the guide part 40 on the inside circumferential face of the barrel 26. Similarly, an outside circumferential face 46 of the second zoom lens holding member 44 holding the second zoom lens 42 is engaged with the guide part 40 on the inside circumferential face of the barrel 26 also, and in respect to the movement in the direction of the optical axis, the second zoom lens holding member 44 is slided and guided by the guide part 40. Thus, the movement of two zoom lens holding members 36 and 44 in the direction of the optical axis is guided by the guide part 40 on the inside circumferential face having the same dimensions of the inside diameter of the barrel 26.
