In a camera according to the present invention, an edge portion of a lens barrel unit is projected and arranged from a front cover. The lens barrel unit is covered with a front cover cylindrical member connected to the front cover, and a front exposed portion of the front cover cylindrical member is covered with an exterior cylindrical member as a detachable (before-attaching) metal cylindrical member. The exterior cylindrical member is positioned and is fixed by an stop claw on the front-cover side. A C-shaped stop portion cover having flexibility is made flexible and is attached around the stop claw portion, and is fixed by a screw. The restriction on design is reduced on the appearance for covering the lens barrel unit of the camera, and a camera exterior portion can be made of metal.
