PROBLEM TO BE SOLVED: To suppress the leakage of noise from a through-hole group to a passenger compartment in the case of second specifications inhibiting fitting of a speaker.SOLUTION: The body part 12 of a vehicle instrument panel 11 includes a speaker fitting part 16 in an inner surface side, and a plurality of slits 23 surrounding the opposite part 21 of the speaker. A garnish 25 has a through-hole group 26 for transmitting a speaker generation sound, and covers an area surrounding all the slits 23 from the outer surface side of the body part 12. In first specifications permitting fitting of a speaker, a through-hole 18 is formed to transmit the speaker generation sound to the body part 12 by cutting a connection part 22 between the slits 23. In second specifications inhibiting fitting of the speaker, the cutting part 22 is not cut to leave an opposite part 21 in the body part 12. In a sound transmission space A1 between the slit 23 and the through-hole group 26, garnish side blocking walls 31 and 32 and a body side blocking wall 33 for blocking a linear sound transmission path R1 from the slit 23 to the through-hole group 26 are provided.SELECTED DRAWING: Figure 4 |
