タ。 A motor circuit that drives the air conditioning door, a potentiometer that detects the opening degree of the air conditioning door, and the air conditioning door detects the control signal based on the opening degree signal from the potentiometer and the control signal given from the outside. In the actuator for driving an air conditioning door, the actuator includes a comparison control circuit that controls the motor circuit so that the opening degree corresponds to the opening degree, and a first power supply terminal that supplies power to the motor circuit and the comparison control circuit; a second power terminal for supplying power to the yometer, and connects the first power terminal and the second power terminal via a diode whose forward direction is a direction from the second power terminal to the first power terminal. Air conditioning door drive actuator connected to.
