Abstract
A misfuelling prevention apparatus for vehicles can prevent a diesel vehicle from being filled with a wrong fuel. The apparatus for vehicles may include an upper housing at an entrance of a filler neck, an internal housing located at a bottom of the upper housing while being supported by an interior of the filler neck, a stopper and a stopper spring, and a flapper and a flapper spring. The stopper may be at one side of the internal housing to be rotated around a pin by a contact with an oil gun. One end of the flapper may be rotatably installed in a pin structure at an opposite side of the internal housing with respect to the stopper and the other end of the flapper may be caught in a recess of the stopper. The flapper is to be pushed and selectively opened by the oil gun.
