PURPOSE:To carry out the defroster blow-out and heater blow-out according to the temperature difference in the vertical direction without reducing the vent blow-out wind quantity by turning a subdamper so that the subdamper is set parallel to the stream of the wind directed to the vent blow-out port, when a temperature control damper is at the coldest position. CONSTITUTION:A defroster blow-out port 13, vent blow-out port 14, and a heater blow-out port 15 are opened on the opposite side to a communication port 12 which communicates to an inside/outside air selecting box 3 of a heater case 4 which forms a part of a ventilating passage 1. Inside the heater case 4, a heater core 16 is arranged, and a cooling air passage 17 is formed on the side part. A temperature control damper 19 is pivotally installed at the front edge of the heater core 16, and a subdamper 20 is arranged on the downstream of a cooling air passage 17 and on the upstream side of the defroster blow-out port 13. In this case, when the temperature control damper 19 is at the coldest position, the subdamper 20 can be turned so that the subdamper 20 is set parallel to the stream of the wind directed to the vent blow-out port 14. |
