PROBLEM TO BE SOLVED: To provide a liquid tank having a sufficient strength capable of adjusting the volume thereof according to the actual storage amount. SOLUTION: The liquid tank 10 comprises a variable volume part 12 capable of varying the volume and a fixed volume part 11 with the fixed volume are made to communicate with each other, to be integrally formed. By changing the volume in the variable volume part 12, the volume of the entire tank can be adjusted. Further, since the fixed volume part 11 is integrated with the variable volume part 12, the strength as the entire tank can be maintained. COPYRIGHT: (C)2005,JPO&NCIPI
