PROBLEM TO BE SOLVED: To provide a lens housing for a bending optical system constituted so that a mechanism member contributing to lens performance and a mechanism member not contributing to the lens performance are separately assembled and the mechanism member contributing to that is singly controlled. SOLUTION: A shutter mechanism arranged concentrically with an incident optical axis, a diaphragm mechanism and a zoom mechanism are constituted to be incorporated from a direction perpendicular to the incident optical axis with a straight advance guide 2 extended along the incident optical axis as opposition.
