PROBLEM TO BE SOLVED: To prevent a cartridge from being drawn out from a cartridge holder under a state where pressure air is introduced. SOLUTION: An elastically deformable region 65 is formed at a part of the outer case 9 of an ink cartridge and an engaging body 66 is provided in that region. When the region 65 is deformed by introducing pressure air, the engaging body 66 projects to engage with an engaging part, e.g. a through hole, formed on the cartridge holder side before being locked.
