PROBLEM TO BE SOLVED: To provide a lens housing for an inflection optical system having improved stability in mounting an assembling holder and a lens, and which is excellent in mass productivity. SOLUTION: The housing is provided with hollow parts V2 and V3 where a linear guide rod GR extending in parallel to an optical axis and a movable lens holding frame can be assembled from one direction and hollow parts V2 and V3 where lens group assembling holders 2 to 5 can be moved in a direction vertical to the optical axis, and the housing can be attained by die-draw molding in one direction.
