ABSTRACT:
A fuel vapor control apparatus halts deterioration in operating characteristics of a fuel control valve at the time of fuel supply and prevents fuel vapor from being discharged into the atmosphere through a filler pipe. The fuel vapor control apparatus prohibits fuel vapor from flowing toward a filler pipe by closing a fuel drop passage at the time of fuel supply. A fuel vapor control valve is configured as a diaphragm valve made of a flexible material, and a diaphragm holder moving integrally with the diaphragm valve is provided at the center thereof. Furthermore, the fuel drop passage as a communication hole is formed in the diaphragm portion at a location radially outward of the diaphragm holder, which is provided with an umbrella portion for opening and closing the fuel drop passage.
