Abstract
A fuel level gauge provided with a remaining-amount warning apparatus is arranged so that an indicating needle for indicating the amount of fuel remaining in a fuel tank operates in accordance with a change in the resistance of a resistor device consisting essentially of a resistance plate having a resistor and a sliding element capable of sliding on the resistor in accordance with a liquid level change in the fuel tank. A warning means for issuing a warning when the amount of remaining fuel reaches a predetermined amount also operates by utilizing the resistor device. In such a fuel level gauge, the warning means is activated by a circuit disposed to connect a remaining-amount warning point and the warning means, the remaining-amount warning point being the position on the resistor at which the sliding element is positioned when the amount of remaining fuel reaches a predetermined amount which requires issuance of a warning.
