PROBLEM TO BE SOLVED: To provide a novel sealing device for a fluid pressure vessel and a mounting mechanism attached to the fluid pressure vessel, and to provide a sealing property between the mounting mechanism and a non-metallic inner liner of the pressure vessel. Improved, and integrity can be maintained at low and high temperatures. SOLUTION: The fluid container 40 has an outer shell 44 and an inner liner 52 in the outer shell 44. The inner liner 52 has lips 84, 88 having an annular bead 88a, and the outer shell 44 has a boss 60. The boss 60 includes a neck portion 68 fitted into the outer shell 44, a flange portion 72, and a cylindrical hollow portion 64, and the lip portions 84 and 88 are provided below the flange 72 of the boss 60. Extends radially inward, Extending upwardly through the hollow portion 64 of the boss 60, its annular bead 88a rests on the shoulder 80 of the boss 60, the adapter 90 has a lower insert having an annular recess 110, The lower insertion portion is fitted into the boss 60 above the shoulder 80, The annular recess 110 has an O-ring 114 protruding from the recess 110 to abut and seal the annular bead 88a. |
