An erroneous refueling prevention device restricts or allows insertion of a refueling gun into a refueling passage depending on an outer diameter of the refueling gun. The device includes a flap (4) configured to open or close the refueling passage by a turn of the flap about a first turn pivot (4i); and a switch (6) configured to be unlocked from the flap (4) by a turn of the flap (4) to a half-opened state, and to turn about a second turn pivot (6c). The switch (6) includes a protrusion detector (6d) configured to, in response to the turn, project to a position where the protrusion detector faces the refueling passage. The switch (6) restricts or allows a turn (4) of the flap from the half-opened state to a fully-opened state, depending on a turn amount of the switch to be determined by a contact relationship between the protrusion detector (6d) and the refueling gun.
