PURPOSE:To improve the efficiency by feeding conditioned air produced from an air-conditioning unit at the front section through a duct coupled immediately after a heat-exchange core to the rear seat side and regulating with a damper thereby performing the temperature adjusting at the rear seat side independently. CONSTITUTION:Upon push-down of temperature adjusting lever 18 around a fixed shaft 19, a damper 16 will rotate through a supporting arm 17 by the angle corresponding with the push-down width of lever 18 into the duct 1 through rotary shaft 20 thus to take the room air into the duct 1. A blower 3 is provided in the duct 1 in downstream of damper 16 to feed the room air near the rear seat forcefully through a feed port 2 into the duct 1 thus to mix the room air and cold wind to be fed from the front of duct 1 and feed through rear blow-out port 15 toward the rear seat. Rotation of blower 3 can be adjusted through adjusting mechanism provided at the rear seat side while the air flow to be fed through the rear blow-out port 15 can be adjusted independently from the front seat resulting in improvement of fan efficiency. |
