PROBLEM TO BE SOLVED: To provide a fueling nozzle with which a time required for fueling can be shortened by minimizing occurrence of bubbles in an oil such as light oil or kerosine to prevent the fueling from stopping before a tank is full, and further to minimize the oil dripping when removing the nozzle from the tank to prevent hands or clothes from getting contaminated with the oil. SOLUTION: A grip (3) and a discharging pipe (4) are provided on a nozzle body (2). The discharging pipe (4) is equipped with an air flow duct (25) opened (26) in the vicinity of its tip. The duct (25) communicates with a negative pressure generating portion (7) and an automatic closing mechanism (6). When the opening (26) is closed, a negative pressure generated in the negative pressure generating portion (7) is transmitted to a diaphragm chamber (28) of the automatic closing mechanism (6) to have a diaphragm (16) sucked and a main valve (5) unlocked to stop fueling. The fueling nozzle (1) thus constituted has a stretching tube (31) provided on the discharging pipe (4), a resistor (32) is provided on the tube (31), and the stretching tube (31) is contracted toward the discharging pipe (4).
