PROBLEM TO BE SOLVED: To provide a power fuel device of a sliding valve type caburettor which can improve supplying responsiveness of the power fuel with respect to negative pressure fluctuation in an intake passage and linearity of the power fuel. SOLUTION: Power fuel is controlled by a power jet 6, and supplied into an intake passage 2 through an aperture 10A of a power nozzle 10. The aperture 10A of the power nozzle 10 is formed on a position lower than a center B of the intake passage 2, within a range of one fourth of a diameter A of the intake passage 2 toward an upstream side from a side surface 3A on an air cleaner side of a sliding throttle valve 3, on respectively both sides of a longitudinal axis X-X of the intake passage 2 serving as a reference line.
