PROBLEM TO BE SOLVED: To provide an attachment mechanism in which gas leakage in a bladder is suppressed and detachment of the bladder is simplified.SOLUTION: The attachment mechanism comprises: an upper ring 24 attached inside of a bladder 22; a storage can 28 extending downward from a lower face of the upper ring 24; a lower ring 26 having a cylindrical side part 56 and a bottom 58 having an opening therein, and disposed outside of the bladder 22; and a seal ring 12 disposed on an upper face of the bottom 58 of the lower ring 26 and having a shape corresponding to a shape of a chamfer part 44 of a clamped part 38. The clamped part 38 is held in a space surrounded by the upper ring 24, lower ring 26, seal ring 12 and storage can 28. The bottom 58 of the lower ring 26 has holes 60 for bolt, penetrating to the lower face from the upper face of the lower ring. When the lower ring 26 on which the seal ring 12 is disposed, is viewed from an upper side, the seal ring 12 is cut at positions of the holes 60 for bolt, such that, the holes 60 for bolt can be viewed.SELECTED DRAWING: Figure 4 |
