A structure for guiding fuel evaporation gases in a canister for automobiles is disclosed. The gas guide structure in the canister of this invention is free from a partition, which has been typically arranged in the upper section inside the upper case of the canister, but has a mounting nipple which is provided on the top center of the upper case. An evaporation gas guide unit is tightly fitted into the mounting nipple. The gas guide unit comprises a nipple holder and fitting part which are preferably cast as a single structure. The nipple holder has the gas inlet and outlet nipples, while the fitting part is fitted into the mounting nipple in order to airtightly mount the unit to the canister. The structure appropriately controls flow of the evaporation gases inside the canister filled with active charcoal, thereby preventing quick failure of the charcoal and lengthening the expected life span of the canister, and improving the durability of an evaporation gas control device.
