Abstract
Provided is a fuel amount measuring device for a vehicle positioned in a fuel tank of the vehicle to thereby measure an amount of remaining fuel. The fuel amount measuring device is implemented as a mechanical fuel amount measuring device including a base body, a resistive substrate, a retainer, and a contactor contacting the resistive substrate, wherein the resistive substrate and the contactor include a conductive film positioned therebetween and coated with a conductive material, such that the contactor and the resistive substrate are connected to each other by the conductive film. With the fuel amount measuring device, abrasion of the resistive substrate is prevented, thereby making it possible to improve durability of the fuel amount measuring device. In addition, the base body and the conductive film are closely adhered to each other, having the resistive substrate therebetween, such that the resistive substrate does not contact fuel, thereby making it possible to prevent corrosion of the resistive substrate. As a result, it is possible to comparatively accurately measure an amount of remaining fuel
