ABSTRACT:
A canister structure for absorbing fuel vapor in the fuel tank and supplying the fuel vapor into the engine together with purge air is provided. The canister structure includes a canister body filled up with absorbents for absorbing the fuel vapor, a purge pipe connected to the canister body for introducing the purge air into the canister body and a separator for removing moisture contained in the purge air. To the separator, the purge pipe is connected downwardly. The separator is provided on the bottom side with an air inlet of which diameter is larger than that of the purge pipe. With the above-mentioned arrangement, since the separator is so formed as to have a diameter larger than that of the purge pipe, it is possible to reduce a flowing speed of the purge air by means of the separator, so that moisture contained in the purge air can be trapped and eliminated by the separator certainly.
