PROBLEM TO BE SOLVED: To confirm a liquid fuel amount even during use wherein a fuel tank is installed to a kerosene fan heater, in a situation wherein the circumference is dark. SOLUTION: An indication part for indicating the liquid fuel amount is provided on the upper face of the fuel tank. The indication part has an indicator 22 moving according to the liquid fuel amount, a scale plate 23 marked with graduations, and a back plate 24, and at least one of them is formed of a luminous material. When installing the fuel tank to the kerosene fan heater, the indication part is exposed to the outside. The luminous material accumulates light by a light source such as an electric lamp, and emits light when the circumference becomes dark. Thereby, a position of the indicator 22 to the graduations can be visually recognized, so that the liquid fuel amount can be confirmed. COPYRIGHT: (C)2007,JPO&INPIT
