PURPOSE:To surely mount a printed-circuit board unit and to surely prevent a connector from being detached, by a method wherein, when the printed-circuit unit is to be inserted, an arm part is pressed in an insertion direction and one nail part is hooked on a protruding part at a shelf. CONSTITUTION:At a main body of a lever 10, recessed parts 14 and protruding pins 15 situated in these recessed parts 14 are formed on both faces so that a stopper 12 can be mounted. The stopper 12 is composed of an elastic sheet material such as stainless steel or the like (a plastic material may be used); holes 16 on this stopper 12 are fitted to the protruding pins 15 at the lever 10 and are fixed to the main body of the lever 10. If it is necessary to fix these parts more surely, the stopper 12 is fixed by caulking the protruding pins 15 (if the lever 10 is composed of the plastic material, the stopper is to be fixed by a thermal caulking operation.). The recessed parts 14 are formed in order to make both side faces of the lever 10 flat after mounting the stopper 12; their depth is to be equal to a thickness of both side parts of the stopper 12.
