PROBLEM TO BE SOLVED: To provide a fuel vapor treatment equipment capable of preventing the disordering of an air-fuel ratio in a combustion chamber immediately after the start of purging, and improving the exhaust emission. SOLUTION: This fuel vapor treatment equipment is provided with a purge valve 43 on a connecting part of a purge line 42 and a canister 2, in adjacent to the canister. Accordingly, the canister and the purge line are separated when the purge is stopped, which prevents the fuel vapor from being dispersed to the purge line from the canister. Further as the fuel vapor remaining in the purge line is sucked out by the negative pressure of an intake pipe, the fuel vapor does not retain in a space such as the purge line just before the start of purging, which prevents the disordering of the air-fuel ratio in the combustion chamber immediately after the start of purging.
