PURPOSE: To improve working properties in a gasoline service station, besides compactification in structure, by coupling plural car service devices with a pump and controlling them in an efficient manner.

CONSTITUTION: A coupling 16 joining a replacing nozzle for engine oil, torque converter oil, etc., a connector 17 for brake oil replacement, a low-pressure connector 18a and a high-pressure connector 18b for refrigerant replacement of a cooler or an air conditioner are all coupled togerher but a fluid sensor 19 and a valve 20 used in common with these elements are installed in the side of a vacuum tank 7. A nozzle 35 for air charging of a tire is coupled with a pneumatic tank 9 via a valve 34 and also a join coupling 38 via a valve 36 and a pressure sensor 37, a check device 41 of an air filter via a valve 39 and a pressure sensor 40 are all coupled with the tank 9, respectively. Various gas service operations at a gasoline service station can be done with one apparatus alone.
