PROBLEM TO BE SOLVED: To provide an intake duct which can prevent the intrusion of water droplets which have been coagulated by a metal gauze, and have trickled down along the metal gauze by surely collecting them.SOLUTION: An intake duct 1 of a vehicle comprises: a duct main body 4 which is opened with an air inlet 3 formed at an upper side, and forms a shell structure; a looper 5 which covers the air inlet 3, and inhibits the direct intrusion of rainwater; and a metal gauze 6 which is interposed inside the looper 5, and prevents the suction of fine foreign matters. A drip channel 7 for receiving water droplets W trickling down along the metal gauze 6 is formed at an inner wall face immediately below the air inlet 3 in the duct main body 4, and the water droplets W are guided to a prescribed water collection part 8 in the duct main body 4 via the drip channel 7.SELECTED DRAWING: Figure 2
【課題】金網で凝集して伝い落ちた水滴を確実に回収してダクト本体内への侵入を防止し得る吸気ダクトを提供する。【解決手段】車両の吸気ダクト1に関し、空気取入口3を上側に開口して外殻構造を成すダクト本体4と、前記空気取入口3を被覆して雨水の直接的な降り込みを阻むルーバー5と、該ルーバー5の内側に介装されて細かな異物の吸い込みを防止する金網6とを備え、前記ダクト本体4における空気取入口3直下の内壁面に前記金網6を伝い落ちる水滴wを受け止めるドリップチャンネル7を形成し、該ドリップチャンネル7を介して前記水滴wを前記ダクト本体4内における所定の水回収部8へ導き得るように構成する。【選択図】図2
