A vapor separator tank for which the separate connection to a canister is not necessary. The inside of a chassis, made of resin, of the vapor separator tank is divided by a wall into a fuel accumulating chamber and a canister chamber. A communication passage is integrally provided on the upper lid of the chassis, and the communication passage communicates the fuel accumulating chamber with the canister chamber. A check valve is provided in the communication passage at the portion thereof connecting to the fuel accumulating chamber. Fuel is supplied from a fuel tank to the fuel accumulating chamber, and when the pressure of evaporated gas in the fuel accumulating chamber reaches a prescribed value, the check valve opens, and the evaporated gas is ejected to the canister chamber. A first outlet connected to an intake pipe of an engine is provided on the uppermost surface of the canister chamber. The canister chamber is filled with activated charcoal, and the evaporated gas is discharged to a scavenging passage via a second outlet provided on a bottom surface of the canister chamber.
