換弁。A diaphragm that is in a non-operating position when the engine is stopped and is activated by manifold pressure while the engine is running and is held in the operating position by suction by a solenoid, and a canister that is connected to the diaphragm and when the diaphragm is in the non-operating position. - A fuel evaporation prevention switching valve for a carburetor equipped with a valve body that opens a side passage and closes an air vent side passage and closes a canister side passage and opens an air vent side passage when the diaphragm is in the operating position, during engine operation. The fuel evaporation prevention switching valve for a carburetor is characterized in that the diaphragm is configured to be maintained in an operating position by applying pressure to the diaphragm partially upstream of the carburetor venturi.
