PROBLEM TO BE SOLVED: To provide a vehicular air conditioner capable of increasing a blowoff temperature while preventing a window from being clouded right after starting an engine. SOLUTION: A feedback passage 23 to make a defroster blowoff passage 17 communicate with the upstream of a blower 3 is provided, and a door 24 to open and close the feedback passage 23 is provided. Thereby, a blowoff temperature can be raised without increasing an amount of inside air to be mixed by feeding back a part of air-conditioned air through the feedback passage 23 to heat it again, when an amount of heating by a heater core 7 is not much right after starting an engine. As a result, the blowoff temperature can be raised while preventing a window from being clouded. In addition, since the feedback passage 23 is provided in a blowoff passage (a defroster blowoff passage 17) other than a foot blowoff passage 20, bad influence (unbalanced temperature distribution) on air-conditioned air blown out from the foot blowoff passage 20 composing a main air passage for heating operation can be suppressed to the minimum.
