According to the present invention, a sound absorption and insulation member (13), which is a plate-like member that is bent so as to alternately abut a first partitioning member (11) and a second partitioning member (12), has a plurality of hollow protruding sections (15) that protrude so as to fill the gap between the respective partitioning members. A first space part and a second space part are formed between the first partitioning member (11) and the second partitioning member (12), wherein the first space part is inside the protruding sections (15) and closed by the first partitioning member (11), and the second space part is provided between the neighboring protruding sections (15) and closed by the second partitioning member (12). The first space part and the second space part areconnected by a communication part (30) that is formed as a portion of the protruding sections (15) and communicates the inside and the outside of the protruding sections (15). A second space part-sideopening of the communication part (30) is provided to a side wall part of the protruding sections (15) arranged between the first partitioning member (11) and the second partitioning member (12).
吸隔音构件(13)是以交替地与第一划分构件(11)和第二划分构件(12)抵接的方式弯曲形成的板状构件,具有多个中空的凸部(15),该凸部(15)以填埋两个划分构件之间的间隙的方式突出,在第一划分构件(11)与第二划分构件(12)之间,形成有被第一划分构件(11)封闭的凸部(15)内的第一空间部和设置在相邻的凸部(15)彼此之间且被第二划分构件(12)封闭的第二空间部,第一空间部与第二空间部通过连通部(30)而相连,该连通部(30)由凸部(15)的一部分形成且将凸部(15)的内外连通,连通部(30)的第二空间部侧的开口设置于配置在第一划分构件(11)与第二划分构件(12)之间的凸部(15)的侧壁部。
