PURPOSE:To facilitate the attachment of a lens without spoiling its function by providing vertically at least two fixing projections which has freely elastic deformation in a radial direction of the contacting surface between a support member and the lens and forming fitting holes for the fixing projections in the contacting surface of the lens. CONSTITUTION:Respective fixing projections 16 of a lens frame 13 are fitted in fitting holes 21 of the lens 14, and lock parts 18 of the fixing projections 16 which project from the fitting holes 21 are spread until end parts of the lock parts 18 abut on the lens edge 20 of the lens 14. In this state, the lens 14 is held fixedly in the lens frame 13 so that its radial movement is restricted without any radial stress due to the elastic deformation of a shaft part 17 and the axial movement is controlled while the contacting surface 22 of the lens edge 20 contacts the contacting surface 15 of the lens frame 13 by the elastic deformation of the lock parts 18. Consequently, the lens is attached to the lens frame compactly and easily without spoiling the lens function. |
