PROBLEM TO BE SOLVED: To provide an evaporative fuel feeing device for an internal combustion engine capable of efficiently increase the amount of evaporative fuel to be supplied to an internal combustion engine. SOLUTION: This evaporative fuel feeding device for an internal combustion engine comprises a fuel tank 2 as a fuel reservoir device for reserving liquid fuel R, a jet pump 3 as a gas discharging device for discharging gas (air) from a gas discharging opening 3a into the liquid fuel R (liquid fuel R') in the fuel tank 2, and a float 4 as a discharging opening vertical movement device for increasing the height of the gas discharging opening 3a of the fuel tank 2 from a bottom surface 2a of the fuel tank 2 as the liquid level W1 of the liquid fuel R (liquid level W2 of the liquid fuel R') in the fuel tank 2 becomes higher relative to the bottom surface 2a of the fuel tank 2. The liquid level W1 of the liquid fuel R (liquid level W2 of the liquid fuel R') in the fuel tank 2 is agitated by the gas (air V) discharged from the gas discharging opening 3a. Thus, the amount of evaporative fuel S to be supplied to the engine is increased. COPYRIGHT: (C)2005,JPO&NCIPI
