特徴とする気化器装置。 An air bypass is provided that communicates between an air passage upstream of the bench lily portion and a mixture passage downstream of the throttle valve, and the air bypass is provided with a bypass on-off valve that is energized to be in a normally closed state; A carburetor device for an internal combustion engine is provided with an operation stop lever that opens the bypass on-off valve and closes the throttle valve, and the operation of opening and closing the valve by the operation stop lever is performed by stopping the operation of the operation stop lever. The bypass on-off valve begins to open at the same time as the operation starts, and the air bypass is rapidly opened by the operation stop operation of the operation stop lever, and the bypass on-off valve is fully opened prior to the time when the throttle valve is fully closed. A vaporizer device characterized by:
