A running guide system for an automotive vehicle planned for running in a sightseeing area or the like. Special running data including right or left turn, passage through a tunnel, running in a predetermined direction and passage on a slope are stored in a cassette tape together with distance data representing the distance from a start point in the form of a plurality of check point data. By collation of the running distance data actually measured and the special running condition data with the stored data, the automobile is guided audibly or visually. Geographical data or sightseeing data are also recorded in the cassette tape and reproduced in voice from time to time. When the automobile is displaced from the planned running route, an alarm is issued. When the automobile is restored to the planned running route, the planned running guide is restored.

An assembling method of a fuel injection valve for fuel injection into an internal combustion engine, the fuel injection valve including a cylindrical valve body having a fuel passage therein and a through-hole made in a direction of the axis thereof and a cylindrical nozzle coupled to the valve body and having a plurality of injection holes for dividing the fuel exited from the through-hole into a plurality of parts and for injecting the divided fuel parts into the engine. The assembling method comprises the steps of coupling the nozzle to the valve body, rotating the valve body relative to the nozzle, and stopping the rotation of the valve body when the through-hole takes a desirable position relative to the injection holes and fixedly securing the nozzle to the valve body. Preferably, an end portion of the valve body is tapered conically and the nozzle has at least one edge portion at its inside so that the edge portion comes into contact with the tapered portion when the nozzle is coupled to the valve body, the edge portion being made of a material whcih is deformed non-elastically in response to application of a force. The edge portion is crushed flat when the nozzle is coupled to the valve body.

In a speed display device of the numerical display type which comprises a speed sensor for producing an electric speed signal indicative of a travel speed of the vehicle, and an electric display responsive to the speed signal for providing a numerical display indicative of the travel speed of the vehicle, the improvement comprises an electric control device responsive to the speed signal for successively enlarging the size of the numerical display in accordance with rise of the speed level. Alternatively, the electric control device may be arranged to be responsive to the speed signal for successively inclining the shape of the numerical display in accordance with rise of the speed level.
