OIL FEEDING NOZZLE PROVIDED WITH FUNCTION FOR JUDGING KIND OF OIL

PROBLEM TO BE SOLVED: To simplify structure and to shorten the time for judging the kind of oil. SOLUTION: A vapor suction and vent hole 4 on a nozzle part, an air pump 16 communicating with the vapor suction and vent hole 4 on a pipe body part, a gas sensor 12 connected with the air pump 16, an air pump controlling means 19 for making the air pump 16 execute evacuating action, successively sucking action and furthermore evacuating action and a means 20 for judging kind of oil for judging existence of gasoline vapor by output of the gas sensor 12 during air sucking action, are provided. As sucking action is performed before an automotive fuel tank is inserted, in case of a gasoline car with high vapor concn., air contg. vapor with high concn. flows into the gas sensor 12 approximately at the same time as a nozzle is inserted to judge a gasoline car.
