ABSTRACT:
A heater unit of an air mixing apparatus for an automotive vehicle includes a core case for housing a heater core and a distribution case communicating with the core case. The distribution case includes a vent duct connecting port connectable to a vent duct previously fixed to an instrument panel; at least one defroster duct connecting port connectable to at least one defroster duct also previously fixed to the instrument panel; and in particular, a guide duct connectable to a side vent duct extending to a driver seat side and fixed to a vehicle body. Since the guide duct is additionally included with the distribution case, it is possible to previously fix the vent duct extending to the front passenger seat side and defroster ducts to the instrument panel, so that the duct assembly workability is improved markedly and the ducts can be reliably fixed to the instrument panel.
