The present invention relates to a fuel mixing prevention device fixed to an oil filling port of a diesel automobile to prevent refueling of gasoline, comprising: an insertion member into which a diesel supply nozzle is inserted; and a support member integrally formed in the insertion member and having an end fixed to an inner wall of the oil filling port. The insertion member has two wires having a reverse U-shape, arranged vertically, and coupled to upper ends. The support member is bent upwards from each of the ends of the insertion member and extends outwards from the insertion member in an open state. A lower fixing plate is fixed to a lower portion of the insertion member. An upper fixing plate is fixed to an upper side of the lower fixing plate, in which a bolt insertion hole is formed. A moving plate with a bolt fixing hole formed therein is provided between the upper and lower fixing plates and moves up and down according to rotation of an extended bolt inserted into the bolt insertion hole. A connection member has one end installed on an upper surface of the fixing plate and the other end fixed to an end of the support member. According to the present invention, a gasoline supply nozzle is prevented from being inserted into an oil filling port of a diesel automobile, thus fundamentally preventing fuel mixture. In addition, a structure of the fuel mixing prevention device is very simple, thereby reducing manufacturing process, obtaining economical efficiency, and being easily applied to an automobile in use, as well as to a new vehicle. |
