To more efficiently absorb and insulate sound emitted from a plurality of sound sources with a comparatively simple structure.SOLUTION: A sound absorbing/insulating member 13 is a plate-like member which is bent-formed to mutually abut on a first partition member 11 and a second partition member 12 and comprises a plurality of hollow projections 15 projected to fill a gap between the partition members. A first space in the projection 15 blocked by the first partition member 11 and a second space which is arranged between the adjacent projections 15 and is blocked by the second partition member 12 are formed between the first partition member 11 and the second partition member 12. The first space and the second space are connected at a communication section 30 which is formed by a part of the projection 15 and communicates inside and outside the projection 15, and an opening on the second space side of the communication section 30 is formed on a side wall section of the projection 15, which is arranged between the first partition member 11 and the second partition member 12.SELECTED DRAWING: Figure 7
【課題】比較的シンプルな構成によって、複数の音源から発せられる音をより効率的に吸音及び遮音することにある。【解決手段】吸遮音部材１３は、第一区画部材１１と第二区画部材１２とに交互に当接するように曲げ形成されている板状部材であって、両区画部材の間の隙を埋めるように突出している中空の凸部１５を複数有し、第一区画部材１１と第二区画部材１２の間には、第一区画部材１１で閉塞された凸部１５内の第一空間部と、隣り合う凸部１５同士の間に設けられ且つ第二区画部材１２で閉塞された第二空間部とが形成されており、第一空間部と第二空間部は、凸部１５の一部で形成され且つ凸部１５の内外を連通する連通部３０にてつながっており、連通部３０の第二空間部側の開口は、第一区画部材１１と第二区画部材１２の間に配置する凸部１５の側壁部に設けられている。【選択図】図７
