A plate, which is fastened along with the windshield panel by the first fastener and the pair of second fasteners, is disposed on the inboard retainer on the inside of the aircraft. The first fastener can be attached to or detached from a fixing nut, which is fixed on the plate, from the outside of the aircraft, and can be replaced with a suspension fastener on which a wire to be mounted on the windshield can be fitted.
