Summary:PROBLEM TO BE SOLVED: To eliminate a risk that a nozzle enters by providing an oil type sensor at an end of an unloading hose equipped with couplings at both ends, providing a connector at the other end of the unloading hose, and connecting the oil type sensor to the connector via a spiral signal line wound around an outer periphery of the unloading hose. SOLUTION: Couplings 17, 18 are respectively provided at both ends of an unloading hose 16 connecting a coupling 12 of a discharge pipe 10 to a coupling 3 of an injection pipe 2. An oil type sensor 11 for sensing an oil type of an oil type identifying piece 4 is provided in the vicinity of the coupling 18 connected to the coupling 3 of the injection pipe 2, while a connector 20 connected to a connector 15 of an unloading controller is provided in the vicinity of the coupling 17 connected to the coupling 12 of the discharge pipe 10. The oil type sensor 19 is connected to the connector 20 via a spiral signal line 21 spirally wound around an outer periphery of the unloading hose 16. A natural diameter of the spiral signal line 12 is molded to be smaller than an outer diameter of the unloading hose 16.
