(a) A throttle valve installed in the intake passage to adjust the amount of air-fuel mixture supplied to the engine. (b) Float chamber for temporarily storing fuel. (c) A fuel nozzle connected to the float chamber by a fuel passage and protruding into the intake passage upstream of the throttle valve for supplying fuel from the float chamber into the intake passage. B) An inner vent that communicates the upper space of the float chamber with an intake passage upstream of the fuel nozzle. (e) An outer vent provided in the upper space of the float chamber for sending fuel vapor to the fuel vapor adsorption container. (f) a valve body that switches between the inner vent and the outer vent, a diaphragm that drives the valve body, a round that connects the diaphragm and the valve body, and a diaphragm chamber that is arranged within a diaphragm chamber partitioned by the diaphragm. and a spring that presses the diaphragm in a direction in which the valve body closes the inner vent. (g) A check is made to communicate the diaphragm chamber with the intake passage downstream of the throttle valve, and to allow air to flow only from the diaphragm chamber to the intake passage, but to prevent air from flowing in the opposite direction. A negative pressure passage with a valve and a throttle that restricts the air flow interposed in parallel.
