PROBLEM TO BE SOLVED: To provide a refrigerant cylinder that can easily be filled with refrigerant in a short time. SOLUTION: This refrigerant cylinder 10 is provided with a siphon tube 12 and an auxiliary siphon tube 14. The siphon tube 12 is formed in the same structure as a siphon tube installed in a normal refrigerant cylinder. The auxiliary siphon tube 14 is constituted of a cylinder tube 22 vertically disposed in the refrigerant cylinder 10 and having an inlet 32 for taking in the refrigerant in the refrigerant cylinder 10 formed therein, a piston 24 movable by the self-weight thereof in the cylinder tube 22, and a discharge tube 26 connected to the cylinder tube 22 and discharging the refrigerant 16 taken in the cylinder tube 22. Thus, the refrigerant 16 taken in the cylinder tube 22 can be pushed out to the discharge tube 26 by the movement of the piston 24 in the cylinder tube 22 by its self weight to discharge the refrigerant.
