PROBLEM TO BE SOLVED: To obtain an oil supply tank in which a cap can be removed easily from the fuel intake of a cartridge tank without contaminating fingers with kerosene by coupling an elevating/lowering guide tube with the fuel intake cap through bending of stop clips. SOLUTION: Eight stop clips 19, 19, for example, are provided at the lower end of an elevating/lowering guide tube 13. Rectangular holes 20 are made at the stretching base part of a spring receiving seat provided at the lower end of a fuel intake cap 3 and inserted, respectively, with two stop clips 19, 19. The stop clips 19, 19 are bent after being inserted into the rectangular holes 20 and jointed rigidly to the fuel intake cap 3. The elevating/lowering guide tube 13 and the fuel intake cap 3 are separated by recovering the stop clip 19 from bent state. A knob handle can thereby be replaced easily by a new one upon damage. In other words, the elevating/lowering guide tube 13 is fixed to the fuel intake cap 3 not by welding but by means of the stop clip 19.
