Claims

[Scope of utility model registration request]

A door for temperature control or air volume control from each outlet located in the airflow passage of an air conditioner, a drive mechanism for opening and closing this door, and a door disposed between this drive mechanism and an engine negative pressure source. a vacuum pipe provided therein; a valve means interposed in the vacuum pipe for selectively supplying engine negative pressure or atmospheric pressure to the drive mechanism; An air conditioner for a vehicle, comprising an electronic control circuit that sets a negative pressure conduction state or an atmosphere release state, and operates the drive mechanism based on a control signal from the electronic control circuit to control the door opening degree. In the control device, the vacuum piping is provided with a control valve means that detects a decrease in engine negative pressure by comparing the engine negative pressure with atmospheric pressure, and when the engine negative pressure decreases, the control valve 1. A control device for a vehicle air conditioner, characterized in that the control device operates a means to maintain operating pressure to a drive mechanism.
