Abstract
Two types of activated charcoals having different adsorption and desorption functions are appropriately disposed in a canister. Gas movement is evenly dispersed via an air space and diffuser equipped between the two activated charcoals. Thereby, leakage of fuel vapor from the canister to the atmosphere is minimized without implementing a supplementary component (e.g., a subsidiary canister), and reduction of the consumption amount of the activated charcoal by eliminating a dead volume.
