AIR INTAKE DUCT

PROBLEM TO BE SOLVED: To reduce the cost required for preventing passage of liquid.SOLUTION: An air intake duct 10 comprises a duct body 12 that is provided with an air flow passage 16 for flowing of air in the inside and forms an outer shell, and a receiving part 40 that is provided on the duct body 12 while being located under a lateral flow channel 18 of the air flow passage 16, which extends in the lateral direction. The air intake duct 10 also comprises a flow channel defining part 42 that is formed of a solid resin and closes an opening of the receiving part 40 to define the bottom of the lateral flow channel 18, and an opening part 50 that is provided in the flow channel defining part 42 for allowing liquid to flow down from the lateral flow channel 18 to the receiving part 40.SELECTED DRAWING: Figure 3 【課題】液体の通過防止にかかるコストを低減する。【解決手段】吸気ダクト１０は、空気が流通する空気流通路１６が内側に設けられ、外殻を構成するダクト本体１２と、空気流通路１６の横方向に延びる横流路１８の下側に位置してダクト本体１２に設けられた受部４０とを備えている。また、吸気ダクト１０は、ソリッド樹脂からなり、受部４０の開口を塞いで横流路１８の底部を画成する流路画成部４２と、流路画成部４２に設けられ、横流路１８から受部４０への液体の流下を許容する開口部５０とを備えている。【選択図】図３
