A vehicle air conditioner comprises an air conditioning unit (4) disposed substantially in the middle of the inside of an instrument panel in a widthwise direction of a vehicle, in air blowing unit disposed to a front-passenger's side of the air conditioning unit (4), an intermediate duct for ducting an air from the air blowing unit to the air conditioning unit (4) and a cooling heat exchanger and a heating heat exchanger disposed in the air conditioning unit (4), said air conditioner allowing the air introduced from the intermediate duct into the air conditioning unit (4) to pass through the cooling and heating heat exchangers disposed in the air conditioning unit (4) to produce a conditioned air. In order to improve such a vehicle air conditioner, cooler pipes (90) connected to the cooling heat exchanger and heater pipes (91) connected to the heating heat exchanger are arranged to extend from the same side of the air conditioning unit (4) in the widthwise direction of the vehicle. The cooler pipes (90) and heater pipes (91) are extended from a side wall of the air conditioning unit (4), bent substantially at a right angle, brought into proximity to each other and then extended toward the front of the vehicle, and all the cooler and heater pipes (90, 91) pass through through holes in proximity to each other in a dash panel disposed at the front of the air conditioning unit (4) to locate distal ends thereof in an engine room beyond the dash panel. The air conditioning unit (4) is provided with a temperature control damper for controlling the temperature of a conditioned air by changing the ratio of the flow rate of air passing through the heating heat exchanger to the flow rate of air introduced into the air conditioning unit (4), and a blow-out direction switching damper for changing the blow-out direction of the conditioned air. Drive mechanism and actuators for driving the temperature control damper and the blow-out direction switching damper, respectively, are disposed on the side wall of the air conditioning unit (4) located toward the air blowing unit (Fig. 10).
