装置。 An external intake passage that opens to the outside of the vehicle body and an internal intake passage that opens to the inside of the vehicle body merge on the way to the internal combustion engine, and an external intake passage or an internal intake passage that is located at the confluence of the passages. In a vehicle internal combustion engine provided with a passage switching valve that selectively communicates with the internal combustion engine, an opening/closing driving means having an elastic member made of a shape memory alloy as a power source is connected to the passage switching valve, and the opening/closing driving means Based on the transformation of the elastic member, the passage switching valve is set to close the external intake passage when the temperature is lower than a predetermined temperature, and to close the internal intake passage when the temperature is higher than the predetermined temperature. An intake passage switching device for a vehicle internal combustion engine, characterized by:
