Abstract
A needle valve body (220) has a needle hollow part (230) and a slit (232) extending in an axial direction and opened forward in a tip region. The carburetor body (B) has a body hole (202) receiving the needle valve body (220) in a longitudinally displaceable manner along an axis and a step-part circumferential edge (240a) formed in the body hole (202) and forming an orifice (250) with the slit (232) of the needle valve body (220). By operating the needle valve body (220) to adjust the size of the orifice (250), an amount of fuel supplied to a fuel discharge part (Fout) can be adjusted.
