The panel fixing bracket includes an inner plate fixing frame(210), an insulator contact frame(220), a side wall fixing frame(230), and a calking frame(240), which are integrally formed. The insulator is equipped between an outside panel(100) and the panel fixing bracket. The caulking is equipped between an outer plate(130) of the outside panel and the calking frame. The foreign matter blocking part, one end of which is inserted in the caulking, covers the exposed portions of panel fixing bracket, insulator and caulking.
