Zusammenfassung:	To provide a ventilation hole terminal member, etc. that have improved an effect to reduce the sound of middle and high frequency bandwidths when waterdrops fall and collide.SOLUTION: A ventilation hole terminal member is attached to a ventilation hole formed in an outer wall of a building, and includes a hood part 3 protruding from an outer wall surface of the building to the outside of the building, and a waterdrop receiving plate 5 provided on a top plate 32 of the hood part 3 through an elastic support body 4. A primary natural frequency fof a vibration proofing body composed of the waterdrop receiving plate 5 and the elastic support body 4 is set to be a frequency of 16 Hz or higher and 125 Hz or lower in an octave band.SELECTED DRAWING: Figure 1 【課題】水滴落下衝突時における中高周波数帯域の音を低減させる効果を向上させた換気口端末部材等を提供する。【解決手段】本発明の換気口端末部材は、建物の外壁に形成された換気孔に取付けられる換気口端末部材であって、建物の外壁面より建物の外側に突出するフード部３と、フード部３の天板３２の上に弾性支持体４を介して設けられた水滴受板５とを備え、水滴受板５と弾性支持体４とで構成される防振体の一次固有振動数ｆ０が、オクターブバンドの１６Ｈｚ以上で１２５Ｈｚ以下の周波数となるように設定されたことを特徴とする。【選択図】図１
