Abstract

PURPOSE:To facilitate alignment of the axial center of a focusing lens and an optical axis by operating a lens holding member, which has a cylindrical part covering a cam groove part from the outer wall side of a lens barrel, to rotate said holding member forward and backward around the optical axis with the inside wall part of the lens barrel as a guide. CONSTITUTION:A lens holding member 40 holding a focusing lens 10 is guided rotatably forward and backward around the optical axis by the inside wall part 42 of a lens barrel 16, and has a cylindrical part which is guided reciprocatably in the optical axis direction. The member 40 is constituted of a part holding the lens 10 and a slided and guided part in one body and therefore it is easy to align the axial center of the lens 10 and the optical axis during the movement of the member 40.
