PROBLEM TO BE SOLVED: To restrict intrusion of flame from an oiling port into a fuel tank, and to quickly perform oiling by smoothly exchanging fuel and air in a flame arrestor when oiling, in addition to restriction of intrusion of flame from the oiling port into a fuel tank by using the flame arrestor. SOLUTION: This oiling port device of a vehicular fuel tank is provided with an oiling port 15a in an upper wall 3a of a vehicular fuel tank 3 storing ethanol fuel as fuel for an engine and an oiling guide cylinder 15 extended from the oiling port 15a into the fuel tank 3. A wire netting flame arrestor 21 having a diameter larger than that of the oiling guide cylinder 15 is fitted to the oiling guide cylinder 15 so as to allow the fuel to flow and, on the other hand, so as to prevent intrusion of flame.
