PROBLEM TO BE SOLVED: To provide an evaporated fuel treating device reducing the number of components and an installation space. SOLUTION: When purging evaporated fuel adsorbed by a canister 11, a pump 12 supplies air to the canister 11. An opening and closing valve 26 is opened, and the pump sucks in atmospheric air from a suction passage 25. Since a canister control valve 24 is closed, a flow of air from the pump 12 to the canister 11 is allowed. When operating a brake, the pump 12 decompresses a brake booster 13. The opening and closing valve 26 is closed, and the pump 12 decompresses the brake booster 13. Since the canister control valve 24 is opened, air delivered from the pump 12 is exhausted into the atmosphere from a control passage 23 without flowing into the canister 11. By this, purging of evaporated fuel and power increase of the brake can be achieved by one pump 12, and the number of components and the installation space can be reduced.
