PURPOSE:To prevent a fitting leg from becoming loose by inserting and bending the fitting leg of a metallic net into penetration holes provided around the speaker sound discharging hole part of a cabinet and welding a rib piece provided at the inner surface side of the cabinet onto the fitting leg. CONSTITUTION:A metallic net main body 1 is inserted into the recessed groove 5 of the cabinet 3 made of synthetic resin in which the bending part 1a of an outer circumference has a speaker sound discharging hole part 4, a fitting leg 2 is inserted into the penetration holes 6 of the cabinet 3 and fitted at the cabinet 3 so as to cover the speaker sound discharging hole part 4. The fitting legs are respectively bent between a pair of rib pieces 7 and 7 protruded at the inner surface side of the cabinet 3 and the rib piece 7 is fitted to the cabinet 3 by melting it on the bent fitting leg 2. Thus, the loosing of the fitting leg 2 of the metallic net main body 1 can be effectively prevented. |
