1. An automotive air conditioner comprising:a unit casing; an evaporator disposed in said unit casing; a heater core disposed in said unit casing; a mixing door provided between said evaporator and said heater core so as to be slidably moved, said mixing door moving to thereby cause air passing through said evaporator to branch at a predetermined ratio into (i) a hot air passage where said air is allowed to pass through said heater core and (ii) a bypass passage side where said air is caused to bypass said heater core; a mixing zone into which cold air passing through said bypass passage and hot air passing through said hot air passage are sent, to thereby mix the cold air and the hot air, wherein a surface of said mixing door with which the air passing through said evaporator is brought into contact is expanded at least partially toward an upstream side of an air flow.
