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 configured to open or close the refueling passage by a turn of the flap about a first turn pivot; and a switch configured to be unlocked from the flap by a turn of the flap to a half-opened state, and to turn about a second turn pivot. The switch includes a protrusion detector configured to, in response to the turn, project to a position where the protrusion detector faces the refueling passage. The switch restricts or allows a turn 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 and the refueling gun.
