AIR INTAKE DUCT STRUCTURE

摘要

PROBLEM TO BE SOLVED: To provide an air intake duct structure formed by blow molding of relatively low cost capable of effectively separating water drips. SOLUTION: A duct unit 7 is arranged flush with an upper surface and a side surface of a cab in its back surface and formed with an air introducing port 2 in the upward side, and a curved surface 9 is formed in a location mutually opposed to the air introducing port 2 in a rear surface of the duct unit 7. Many reverse V-shaped ribs 10 are arranged in the rear surface along a vertical direction. Water and air introduced in the duct unit from the air introducing port 2 are separated in the curved surface 9, and a water drip sticking to the rib 10 is separated in a right/left direction along the rib 10 and discharged from the lower end.
