Claims

[Scope of utility model registration request]

An inside air intake duct is provided in the middle of an outside air introduction duct that communicates with a blower, and a damper that can be switched open and closed between the inside air intake and the outside air introduction duct is installed inside and outside the air conditioning intake duct. In the air switching device, the damper has a substantially U-shaped cross section and coaxial rotation centers at both open ends, and the inside air inlet of the outside air introduction duct connects the damper halfway through the outside air introduction duct. An inside/outside air switching device for an air conditioning intake duct, characterized in that the damper is formed by notching a shape corresponding to the shape of the damper and is movable with respect to the outside air introduction duct via the rotation center.
