To provide a ventilator that restrains the occurrence of the Coanda effect on a member which is inclined such that the opening area of an opening portion increases toward the downstream side.SOLUTION: A ventilator 100 includes: a vertical louver 31 with a knob 32 installed thereon; a pair of sidewalls for rotatably supporting the vertical louver 31 and forming a part of an opening portion 110; and a first inclined member 21 which forms another part of the opening portion 110 between the pair of sidewalls and is inclined such that the opening area of the opening portion 110 increases from the upstream side toward the downstream side in the wind flowing direction. In a maximum angle state in which the vertical louver 31 is rotated so that an upstream end part 31c of the vertical louver 31 is closest to the first inclined member 21, the upstream end part 31c is positioned on the downstream side in the wind flowing direction with respect to an apex 21a. A projection part 6a arranged adjacent to the apex 21a of the first inclined member 21 on the upstream side in the wind flowing direction projects to the inner side of a flow passage 11 with respect to the apex 21a in a direction orthogonal to both an axis of rotation of the vertical louver 31 and the wind flowing direction.SELECTED DRAWING: Figure 2

    【課題】開口部の開口面積が下流側へ向けて拡がるよう傾斜する部材上のコアンダ効果発生を抑制するベンチレータを提供する。【解決手段】ベンチレータ100は、ノブ32が装着された上下ルーバ31と、上下ルーバ31を回動可能に支持し、開口部110の一部を形成する一対の側壁と、一対の側壁の間で開口部110の他の一部を形成し、風流れ方向の上流側から下流側へ向けて開口部110の開口面積が広がるよう傾斜する第1傾斜部材21と、を備える。上下ルーバ31の上流端部31cが第1傾斜部材21に最も近くなるよう上下ルーバ31を回動させた最大角度状態にて、上流端部31cは、頂点21aより風流れ方向の下流側に位置する。第1傾斜部材21の頂点21aに対し風流れ方向の上流側に隣接して配置された凸部6aは、上下ルーバ31の回転軸及び風流れ方向の両方と直交する方向にて、頂点21aよりも流路11の内側に突出する。【選択図】図2
