Zusammenfassung:	To provide a silencer that can suppress increase in installation space and improve noise reduction property.SOLUTION: A silencer 1 includes: a case 4 forming a space 6 communicated to a passage 3 inside a duct; and one or more partition plates 5, 5a-5d installed in the space 6 inside the case. At least one of the partition plates 5, 5a-5d is installed in a position separated from at least part of case inner walls 4b-4e positioned in a surface direction that is parallel to a boundary surface BS between the space inside the case and the passage inside the duct.SELECTED DRAWING: Figure 14 【課題】設置スペースの増加を抑えると共に、騒音低減特性を向上することの可能な消音器を提供する。【解決手段】消音器１は、ダクト内の通路３に連通する空間６を形成するケース４と、そのケース内の空間６に設けられる１または複数の仕切板５、５ａ～５ｄとを備える。その仕切板５、５ａ～５ｄの少なくとも１つは、ケース内の空間とダクト内の通路との境界面ＢＳに平行な面方向に位置するケース内壁４ｂ～４ｅの少なくとも一部から離れた位置に設けられている。【選択図】図１４
