PROBLEM TO BE SOLVED: To provide evaporation fuel treating equipment capable of being simplified and achieving cost reduction while securing a sufficient purge flow rate. SOLUTION: In an internal combustion engine 3 having a supercharger 5 for supercharging on an intake passage 3a, the evaporation fuel treating equipment 1 for temporarily adsorbing evaporation fuel generated inside a fuel tank 21 in a canister 23 and supplying the evaporation fuel to the intake passage 3a is provided with a recirculation passage 24 connected to upstream and downstream sides from the supercharger 5 on the intake passage 3a and recirculating air pressurized by the supercharger 5 from the downstream side to the upstream side of the supercharger 5; a throttle part 25 provided on the recirculation passage 24 and throttling it; and a purge passage 26 connected to the canister 23 and the throttle part 25 of the recirculation passage 24 to supply evaporation fuel adsorbed in the canister 23 to the intake passage 3a.
