Claims

[Scope of claim for utility model registration] An air conditioner case that takes in air through a blower, an evaporator that dehumidifies and cools the air taken in and turns it into cold air, and a heater core that heats this cold air to turn it into warm air. and a distribution box having a mixture chamber that mixes the cold air and the hot air at an appropriate ratio, and the distribution box and the air conditioner case are provided so as to be openable and closable, thereby changing the flow direction of the air. A switching door device for an automobile air conditioner, comprising a switching door, the switching door being divided into at least two main switching doors and a sub switching door, and a switching door for opening and closing the main switching door and the sub switching door. The main switching door is rotatably attached to the drive shaft, and the main switching door and the sub switching door are provided with an engaging protrusion and a recess, respectively, and an elastic member is interposed between the main switching door and the sub switching door in accordance with the shape of the air conditioner case or the distribution box. A switching door device for an air conditioner for an automobile, characterized in that the door and the sub-switching door are configured to open and close integrally or independently.
