摘要

An air conditioning device for vehicles is provided to form a mode door with two dome type doors for improving assembling efficiency of the mode door and guiding air by the dome type doors to reduce ventilation resistance and size of an air conditioning case. An air conditioning case(110) has a blower at an inlet(114), a plurality of vents(111,112,113) at an outlet, and an evaporator(101) and a heater core(102) inside. A temperature control door(120) is installed at a lower side of the evaporator. A mode door(130) opens and shuts the plurality of vents. The mode door includes a first dome type door(131) installed in the air conditioning case rotatably, and a second dome type door(132) installed at the inside of the first dome type door coaxially. The first dome type door and the second dome type door are operated to open and shut two or more vents.
