PROBLEM TO BE SOLVED: To provide an oil nozzle which can be improved in durability even when subjected to repeated operation load. SOLUTION: The oil nozzle 10 includes a nozzle body 11 whose front end is fitted with a delivery pipe 13 having a liquid level detecting opening 35, and whose rear end is connected to an oil hose 17. The oil nozzle 10 is provided with an automatic closing mechanism 15 which operates to close a main valve 14 in response to liquid level sensing, and has a diaphragm 25 in a diaphragm chamber 37 that communicates with a negative pressure generating portion 16 communicating with an opening 35 of the delivery pipe 13 and that operates against an energy-applying force from a spring 29. The diaphragm 25 is composed of an elastic material 25a in a platelike form, and a metal fiber 25b covering the elastic material 25a. COPYRIGHT: (C)2008,JPO&INPIT
