WEATHER COVER

To stabilize a flow of a gas which is discharged outdoors from a weather cover of a type to be installed after being inserted from an indoor side to a mounting port that is formed in a building, by improving such a weather cover, and further, to eliminate the risk that rainwater in rainy weather may be sucked in the application of covering a suction port.SOLUTION: In a main body part 2 of a weather cover, a movable hood 3 which is mounted in a rotatable manner on an inner surface of the main body part closer to a distal end of a bottom wall 7 and is rotated to appear from and disappear into a port hole 8 that is provided in the main body part 2, is provided. An opening 13 which downwardly protrudes outside of the port hole 8 closer to the distal end of the bottom wall at a position where the movable hood 3 is moved outdoors, and is tilted downwards to the front side while being supported on a hood supporting surface 8a around the port hole 8 at a protrusion ending point is created at a lower side than a mounting port Mp.SELECTED DRAWING: Figure 1 【課題】建屋に形成された取付口に屋内側から挿入して設置するタイプのウェザーカバーを改善してそのウェザーカバーから屋外に排出する気体の流れを安定させ、さらに、吸気口を覆う用途での雨天時の雨水吸い込みの懸念も無くすことを課題としている。【解決手段】ウェザーカバーの本体部２に、その本体部の底壁７の先端近くの内面に回動可能に取り付けられて回動により本体部２に設けた口穴８から出没する可動フード３を設け、その可動フード３が屋外に出た位置で底壁先端側の口穴８から下向きに外部に突出し、突出終点で口穴８の周囲のフード支持面８ａに支持されて前下がりの方向に傾いた開口１３を取付口Ｍｐよりも下側に作り出すように構成した。【選択図】図１
