Claims

[Scope of Claim for Utility Model Registration] An outside air introduction mode in which an outside air switching damper and an inside/outside air switching operating means are provided, and the outside air switching damper is switched by the inside/outside air switching operating means to introduce outside air into the vehicle interior; An inside/outside air switching device that selects either an inside air circulation mode or an inside air circulation mode that circulates air inside the vehicle interior includes a sensor that directly or indirectly detects the pressure on the exterior surface of the vehicle interior of the door, and a sensor whose detected value is a predetermined value. An inside/outside air switching control device comprising: control means for setting an inside air circulation mode when the pressure is on the lower pressure side regardless of the operation by the inside/outside air switching operation means;
