を特徴とする風向切換装置。 The flap is provided with a flap that changes the direction of the air blown out from the outlet of the duct, and a shape memory alloy spring that drives the flap according to the temperature change of the air, and the flap is rotatably mounted on a shaft within the duct. In the wind direction switching device, in which one end of the flap and the duct are connected via the shape memory alloy spring, the flap is a hollow body, and a liquid is accommodated in the flap. A wind direction switching device characterized in that the shape memory alloy spring contracts at a temperature above a predetermined memory temperature and expands at a temperature below the predetermined memory temperature.
