发明名称 A PREVENTING STRUCTURE OF WHISTLE NOISE BY VENT DOOR OF AIR DUCT IN VEHICLES
摘要 A structure for preventing whistle noise of a vent door of a vehicle air duct is provided to surround an outer peripheral surface of the vent door by a sealing pad for preventing generation of a gap between the vent door and the air duct, thereby preventing generation of whistle noise and realizing silent room condition. A structure for preventing whistle noise of a vent door of a vehicle air duct includes a duct branched for discharging air from an air conditioning unit to the center of a room and right and left sides. A vent door(7) is rotatively mounted in the duct for alternatively closing an internal space of the duct by rotating with respect to a hinge, and formed with a through-hole(7a) in the center. A sealing pad(10) surrounds a surface and a peripheral surface of the vent door and is expanded by air moving through the duct for blocking an inside of the duct.
