Abstract

PURPOSE:To make construction simple and improve working accuracy by guiding the movement of three movable lens holding members in the optical axis direction by means of the guide part of the inside circumferential surface of the same inside diameter as that of a lens barrel. CONSTITUTION:The outside circumferential surface 18 of a cylindrical part 10 on the inner side of a focusing lens holding member 4 is in an engagement relation with the inner cylindrical part 10 of a lens barrel 14, and its movement in the optical axis direction is slided and guided. The outside circumferential surface 26 of a holding member 24 holding the 1st zoom lens 22 is also so arranged similarly as to be slided and guided by a guide part 20. Similarly, the outside circumferential surface 32 of a holding member 30 holding the 2nd zoom lens 28 is also in an engagement relation with the part 20 and its movement in the optical axis direction is slided and guided by this. Thereby, the guide surface requiring working accuracy of the lens barrel 14 is made to one, and this makes the construction simple and improves working accuracy.
