PROBLEM TO BE SOLVED: To provide a carburetor capable of restraining the change of an attitude from affecting a fuel supply amount. SOLUTION: The carburetor 1 comprises main fuel passages 2 and low-speed fuel passages 3 supplying mixtures of air and fuel sucked from a fuel chamber 9 to intake passages 11 communicating with cylinders of an internal combustion engine. The main fuel passages 2 and the low-speed fuel passage 3 are provided for each of the intake passages 11 arranged in two rows, and located between the intake passages 11 to extend upward from the fuel chamber 9. The low-speed fuel passages 3 extend upward between the two intake passages 11, 11 from the upper walls of the main fuel passages 2, and comprise mixture producing chambers 3a and fuel suction pipes 3b with upper end openings facing the mixture producing chambers 3a. The fuel suction pipes 3b are arranged through the main fuel passages 2 so as to be coaxial with the main fuel passages 2. COPYRIGHT: (C)2010,JPO&INPIT
