Claims

[Scope of utility model registration request]

In a door for an air conditioner that is rotatably supported on a case side and controls air flow, a first magnet is disposed on the door or a door side member that moves together with the door, and the door is A second magnet is fixedly installed on the case side and faces the first magnet in a direction in which magnetic forces repel each other in a state where the flow to be controlled is blocked, and the second magnet is connected to the first magnet on the door or door side member. A door for an air conditioner, characterized in that at least one of the second magnet on the case side is an electromagnet, and the magnetic force of the electromagnet is increased in accordance with an increase in the flow rate of air blown inside the air conditioner.
