Zusammenfassung:PROBLEM TO BE SOLVED: To reduce a pressure loss without sacrificing sound reduction performance by effect of reflection interfere of a sound wave in a curved part of an air channel.SOLUTION: A corner vane 10 is installed in the curved part 58 of an air channel. At least part of the corner vane has acoustic permeability and passage resistance to an air flow passing through the air channel. The corner vane has an outside member 12. The outside member defines a cavity 14 inside thereof.SELECTED DRAWING: Figure 1 【課題】風路の曲がり部における音波の反射干渉の効果による減音性能を犠牲にすることなく、圧力損失を小さくするものを提供する。【解決手段】風路の曲がり部５８に設置するためのコーナーベーン１０が提供される。かかるコーナーベーンの少なくとも一部が音響的に透過性を有し、且つ、風路を通過する気流に対して通過抵抗を有する。コーナーベーンは、外側部材１２を有し、外側部材は内部に空洞１４を画定する。【選択図】図１
