Abstract
An air conditioning apparatus includes a seal wall having a seal surface to which one end surface of an air mixing door is contacted in the maximum heating state. A defroster warm air leading passage is constructed by the seal wall, a warm air guide portion and an inner surface of an air conditioning case. The defroster warm air leading passage is formed in a space opposite to the seal surface of the seal wall at a downstream air side of the seal wall. Because cool air hardly flows through the space opposite to the seal surface of the seal wall and the defroster warm air leading passage is formed by effectively using the space, the size of the air conditioning apparatus for a vehicle can be reduced.
