A canister includes a casing, a fuel reserve well defined at the bottom of the casing, an adsorbent layer provided in the casing for adsorbing fuel vapor, the adsorbent layer communicating with the fuel reserve well at a region of its lower portion and communicating with an atmosphere at its upper portion, a first communication passage defined so that the fuel reserve well communicates with a fuel system of an engine, and a second communication passage defined so that the fuel reserve well communicates with an intake system o f the engine. The second communication passage includes a purge chamber communicating with a region of the adsorbent layer other than the region of the adsorbent layer with which the fuel reserve well communicates, a first fuel outflow passage having a liquid fuel suction port open to the bottom of the fuel reserve well at its lower portion and a nozzle opening positioned in the purge chamber at its upper portion, and a second fuel outflow passage defined over the nozzle opening of the first fuel outflow passage for providing a fuel flow passage extending from the purge chamber to the suction system of the engine.
