Claims

[Scope of utility model registration request]

In an air conditioning duct switching device that switches the direction of flow of conditioned air, the switching device is located at a branch section connecting an upstream air conditioning duct leading to an air conditioner to two types of downstream air conditioning ducts, a cooler duct and a heater duct. a partition plate that partitions the side and the downstream side and has an opening; a partition plate that partitions the opening with one edge thereof and partitions the downstream side of the opening into the cooler duct and the heater duct; and a partition plate that abuts the peripheral edge of the opening and has the same opening. An air conditioning duct switching device characterized by comprising a rotary adjustment plate that partially covers the opening and is rotatably mounted around the center of the opening, and that changes the ratio of the opening area leading to both ducts.
