PURPOSE:To prevent an electrical resistor from being damaged due to overheat, in an air-conditioning device provided with two air-conditioning ducts in combination and a blower having a blast capacity to be controlled by the electrical resistor, by providing a means for inhibiting two blow-out ports from being closed simultaneously. CONSTITUTION:In such a condition that an upper space temperature control lever 31 is shifted to a position in the vicinity of its turn-off position to fully close a face blow-out port 11 by means of a damper 9, during a lower space temperature control lever 32 being shifted to its turn-off position, a projection 44a formed on a bearing section 44 of a rotary actuating rod 42 of the lever 32 abuts against one end of an arcuate groove 43a formed in a bearing section 43 of a rotary actuating rod 41 of the lever 31. Further, when the lever 32 is successively shifted, both rotary actuating rods 41, 42 are rotated integrally with each other so that the lever 31 is moved in association with the lever 32 in the same direction as that of the lever 32, thereby a face blow-out port 11 are slightly opened. With this arrangement, a resistor for adjusting the blast capacity of a blower 24 is always subjected to cooling action. |
