PURPOSE:To enable vaporized fuel to be promptly and surely introduced, by providing a charge port in an intermediate part in the vertical direction of a canister barrel part so that a large head is ensured between a vaporized fuel emitting port of a float chamber and the charge port. CONSTITUTION:The first charge port 19, introducing vaporized fuel from a fuel tank 7, and a purge port 10, supplying adsorbed fuel to an intake pipe 1, are provided in the upper wall of a canister C, while the second charge port 20, for introducing vaporized fuel from a float chamber 5 in a carburetor 2, is provided in an intermediate part in the vertical direction of a canister barrel part Cm. Even if the vertically long formed canister C is arranged in the longitudinal direction in an engine room, a large head can be obtained between a vaporized fuel emitting port 5a of the float chamber 5 in the carburetor 2 and the second charge port 20 of the canister C, and the vaporized fuel from the float chamber 5 is easily introduced to the canister C with small resistance.
