PURPOSE:To make it possible to easily constitute air-fuel mixture supply device in the desired form by providing, freely in exchange, an airflow sensor part comprised of a suction passage section including a negative pressure generation part and a negative pressure inlet and a mixer part comprised of a suction passage section including a negative pressure generation part and a fuel exit. CONSTITUTION:An air flow sensor part AFS is constituted of a first negative pressure generation part 2 formed by throttle part in a suction air passage section 1 and a negative pressure passage 3 having a negative pressure inlet 3a projected in this negative pressure generation part 2. Also a mixer part MIX are constituted of a second negative pressure generation part 5 formed by a throttle part in a suction air passage section 4, a fuel passage 6 having a fuel exit 6a projected to this negative pressure generation part 5 and connected to a float chamber 8 through a fuel measuring jet 7 and a fuel control means 9, etc., such as solenoid valve, etc., for closing this fuel passage 6. Further a throttle valve part THV is constituted by providing a throttle valve 14 inside a suction air passage 13. These each part form a separate unit respectively and can be changed freely with each other.
