通したことを特徴とするアフターバン防止装置。[Claims for Utility Model Registration] An air chamber consisting of first and second negative pressure chambers adjacent to each other via a diaphragm having an orifice, and an air chamber equipped with a port that is opened and closed by a valve body integrated into the diaphragm. In an afterburn prevention device in which an afterburn valve is provided and the second negative pressure chamber and the air chamber are communicated with the downstream side of the throttle valve, the first negative pressure chamber is connected to the negative pressure of the first negative pressure chamber. An afterburn prevention device, characterized in that the afterburn prevention device is connected to the downstream side of the throttle valve via a check valve that opens only when the pressure is deeper than the suction negative pressure of the mixture passage.
