PURPOSE: A canister unit is provided to resolve problems caused by increasing capacity, and using an auxiliary canister. CONSTITUTION: A canister unit comprises an air housing(2), a purge housing(3), a bottom coupling member(10), a lower strainer(20). The purge housing filters hydrocarbon included in evaporating gas, and supplies the gas to an engine when purging gas. The purge housing closely encloses activated carbon filled inside. The bottom coupling member comprises a receiving space without the activated carbon in a lower part of the air housing and purge housing. The lower strainer forms the divergence of air flow to a bottom of the air housing, and forms convergence of the air flow inside the purge housing from the bottom. |
