PROBLEM TO BE SOLVED: To optimize an acceleration pump while maintaining maintainability of a carburetor. SOLUTION: The link structure of a carburetor consists of a drive lever 122 equipped with an action part 125 which abuts on a cam ridge 116b formed on a cam 116 to be slid and a transmission part 126 for enhancing and transmitting swing force by being provided nearer to a spindle 121 taken as a lever swing shaft than the action part 125 and of a driven lever 123 which is freely swingable around the spindle 121 in conjunction with the drive lever 122 and which is equipped with a receiving part 123a receiving the swing force by coming into contact with the transmission part 126 and a coupling part 123b coupled to an acceleration pump taken as a control part for controlling a flow rate of fuel. The transmission part 126 is equipped with a screw mechanism 174 for adjusting an angle formed by the drive lever 122 and driven lever 123 and with a cylindrical cover 171 covering the screw mechanism 174.
