Abstract
A fuel vapor treatment apparatus includes a canister into which fuel vapor generated in a fuel tank is introduced, and the canister is configured to absorb the fuel vapor. An outside air introducing passage is connected with the canister and introduces outside air to the canister. The purge passage connects the canister and a portion of an air intake passage, the portion being located downstream of a throttle valve. The purge valve is provided in the purge passage and switches a channel of the purge passage to one of an open state and a closed state. A flow straightening device is provided in an area extending from a connecting place at which an exit portion of the purge valve is connected to the purge passage, to a connecting place at which the purge passage is connected to the air intake passage.
