A vehicle includes a fuel tank, a canister for temporarily storing vaporized fuel from the fuel tank, a charge pipe that connects the fuel tank and the canister and that introduces vaporized fuel from the fuel tank to the canister, a purge pipe that connects the canister with an intake system of an internal combustion engine, and a vent pipe that connects the canister with ambient air outside of the canister. An opening of the vent pipe is arranged to open upwardly with respect to the vehicle body in a recessed portion that is formed in a hollow shape and opens downwardly in the vehicle body. A space is formed to partially open in an interval to a recessed portion sidewall of the recessed portion, and a locking member is also provided to cover the opening of the recessed portion from below.
