PROBLEM TO BE SOLVED: To provide a fuel vapor processing device capable of improving fuel adsorbing performance by suppressing temperature rise of an adsorber, and capable of suppressing diffusion of fuel vapor in oil supply by sufficiently lowering a temperature of the adsorber.SOLUTION: In an evaporated fuel processing device including a canister 41 mounted on a fuel tank 31 and adsorbing evaporated fuel generated in the tank 31, and a purging mechanism 42 for making the air for desorbing the fuel from the canister 41 and a purge gas including the fuel desorbed from the canister 41, be sucked into a suction passage 23b of an engine 2, the canister 41 is exposed into a cooling passage 51 in which the suction air sucked by the engine 2 is passed, and an adsorber temperature adjusting mechanism 58 is disposed to cool the canister 41 when the sucked air flows into the cooling passage 51. |
