Abstract
A device for preventing a fueling error reliably prevents a fueling error by accurately preventing an insertion of a small-diameter nozzle without blocking an insertion of a large-diameter nozzle whose entrance should be permitted. Even if an end of a nozzle is strongly pressed to left-and-right shutter members (22), the shutter members (22) never rotate and move in an opening direction unless the shutter members (22) slide and move to an outside of a radial direction. Thus, the structure prevents the shutter members (22) from erroneously moving to a position in which the nozzle is allowed to enter from a blocking position.
