A device for displaying information concerning the travel route of an automobile vehicle includes a calculation unit for continuously monitoring the changes in the travel direction of the vehicle on the basis of the direction detected by the direction detection unit, and successively storing change signals corresponding to the amount of change in the travel direction of the vehicle, when the amount of change in the vehicle direction exceeds a predetermined amount, and a distance signal corresponding to the change signal, on the outward travel route, and generating a travel direction signal approximately at a predetermined distance on the basis of the stored change signal and the stored distance signal, on the return travel route. The vehicle travel direction, the distance, and the direction toward the destination or the starting point, and the distance toward a vehicle travel direction change point are displayed on fluorescent indicator tubes.
