PROBLEM TO BE SOLVED: To provide a fuel vapor control structure that can suppress increase in manufacturing cost and can switch pressure loss between an oil filling state and a running state. SOLUTION: The fuel vapor control structure has a fuel vapor guide passage 24 for guiding fuel vapor in a fuel tank 16 from a vent cutoff valve 18 and a rollover valve 19 disposed in the fuel tank 16 to a canister 10 outside the fuel tank 16, a shutter device 23 for detecting fuel filling or non-filling, and a pressure loss selector valve 21 for switching pressure loss in the fuel vapor guide passage 24 in an oil filling state and pressure loss in the fuel vapor guide passage 24 in a non-filling state according to the detection result of the shutter device 23, in which the pressure loss selector valve 21 reduces pressure loss when the shutter device 23 detects fuel filling. The vent cutoff valve 18, the rollover valve 19, the pressure loss selector valve 21 and the fuel vapor guide passage 24 are disposed in the fuel tank 16.
