Abstract
A canister is connected to a fuel tank to adsorb fuel vapor vaporized in the fuel tank and includes a canister housing and a canister main body, which is received in the canister housing and communicates with the fuel tank at one end. The canister housing includes an atmospheric port and a filter chamber, and the filter chamber receives a filter and communicates between the other end of the canister main body and the atmospheric port, which in turn communicates with the atmosphere. The filter includes an active carbon part, an atmosphere-side unwoven fabric and a tank-side unwoven fabric. The active carbon part includes active carbon granules, which adsorb fuel vapor vaporized in the fuel tank. The atmosphere-side unwoven fabric and the tank-side unwoven fabric sandwich the active carbon part therebetween in a flow direction of air, which passes through the active carbon part.
