A fuel supplying apparatus consists of a traveling unit which moves in either of opposite directions, a delivery unit which communicates with the traveling unit and has a fuel hose carrying a fuel supplying nozzle at one end thereof and being lowered and raised, a fixed conduit which communicates with a reservoir and extends uprightly near to the traveling unit, and a folding tube which connects the fixed conduit with the traveling unit. The folding tube is composed of a plurality of non-flexible rigid tubes each of which is pivotally connected and internally communicates with its adjacent tubes at its ends. As the traveling unit moves, the folding tube stretches or contracts without deforming the component tubes.
