特徴とする給油装置。 A pipe connected to a tank at one end, a pump driven by a pump motor and a flow meter for measuring the amount of oil supplied, which are provided in the middle of the pipe, and a flowmeter provided at the other end of the pipe via a hose. A refueling device comprising a refueling nozzle that discharges oil sent from a pump into a fuel tank, a detection element provided in the refueling nozzle and whose resistance value changes depending on the vapor of the oil; a rate of change calculation means for calculating the rate of change in the resistance value of the detection element in a time shorter than the time for the vapor to sufficiently permeate; A determination means is provided for comparing the rate of change corresponding to the oil type and outputting a drive signal to the pump motor or outputting a valve opening signal to the electromagnetic valve provided in the middle of the piping when the two match. A refueling device characterized by:
