PROBLEM TO BE SOLVED: To improve vapor suction efficiency of vapor recovery when oil is fed. SOLUTION: In the oil feed nozzle 3, when a nozzle lever 36 is turned, a valve axis 50 is caused to slide to open a main valve body 31. Thus, an oil liquid fed from an oil feed hose is caused to flow into an oil passage 29 through a negative pressure generating part 30 by the valve opening action of an oil feed valve mechanism 33 and passed through a delivery pipe 26 so as to be delivered into a fuel tank. Wnen the oil liquid flows through the passage 29 in such a manner, the liquid pressure in the passage 29 rises so that the liquid is admitted into a diaphragm chamber 92 of a vapor valve mechanism 81 through a pressure introducing passage opened near the part 30. As a result, a diaphragm 89 is displaced so that a valve body 87 is opened to bring a flow-in chamber 91 into communication with a flow-out chamber 92. Thus, when feeding oil is started, a vapor suction line 47 is opened so that a vapor in a fuel tank is drawn into an underground tank.
