PURPOSE:To aim at enhancing the control feeling and at preventing the control from being confused, in a damper drive mechanism in an automobile air- conditioner which are incorporated with a heater core and a heat pump, by incorporating a link for rotating an air-mix damper and by enabling an actuator to be driven with a control knob being left to be stationary. CONSTITUTION:When an engine is started, a knob 2 on a temperature control lever 1 is displaced to the maximum heating position MAX HOT. As a result, the lever 1 presses a knob for a heat pump switch 50 so that a heat pump and a heater core are driven for heating. The motion of the lever 1 causes a pin 16 at the lower end of an actuator link 13 to be displaced to the position shown by the solid line, through a wire 5. In this condition, the air-conditioning temperature rises, and the lower end of the link 13 is left to be stationary while the link 13 swings due to the provision of a pin 10 and a loose fitting hole 14, even when an actuator 8 actuates an operating rod 9, and thereby a damper 26 is moved. Thus, it is possible to aim at preventing the control from being confused and at enhancing the control feeling. |
