PROBLEM TO BE SOLVED: To realize a waterproof structure of a speaker mounting part without using a packing by arranging a sponge rubber, which is like a paper strip and is not molded, on the whole periphery of a flange in such a manner that it is pulled around and forming a mounting seat for screw locking at the height which corresponds to the height of the sponge rubber, which is compressed, on a mounting face of an ear part where the sponge rubber does not exist. SOLUTION: As for a seal of the whole periphery of a flange 6 for a door speaker P, a sponge rubber 8 like a paper strip is arranged along the whole periphery of a speaker flange 6 in such a manner that it is pulled around. This sponge rubber 8 like a paper strip is obtained as an inexpensive general-purpose product and does not require any special molding. A seal of an ear part 6a of the flange is fixed by using a screw by forming a thick wall part 9 which becomes a mounting seat integrally in a part which corresponds to the ear part of the flange in a peripheral fringe of a waterproof cover K and utilizing elasticity of a waterproof sheet D. Since this flange ear part 6a is tightened directly by using the screw 7 and provides large tightening force, it is possible to obtain sufficient waterproof performance only by elasticity of the waterproof sheet D even if the sponge rubber 8 is not used. |
