Canister for vehicle
In a canister for a vehicle, in order to significantly reduce a leaking amount of evaporated fuel from an atmospheric port of the canister, an introduction port for evaporated fuel and an atmospheric air port for the evaporated fuel are provided in a casing, and an adsorbing material layer communicates between the introduction port and the atmospheric air port. A chamber is provided between the atmospheric air port and a surface on a side of the atmospheric air port in the adsorbing material layer. A leakage preventing adsorbing material layer is arranged within the chamber so that a space layer is formed between the leakage preventing adsorbing material layer and the surface on the atmospheric air port side in the adsorbing material layer and another space layer is formed between the leakage preventing adsorbing material layer and the atmospheric air port.
