PROBLEM TO BE SOLVED: To provide a high pressure vessel capable of surely preventing leakage of gas to the outside with a simple structure.SOLUTION: A high pressure vessel 1 for storing gas or liquid includes a resin liner 10 having a boss 11 outwardly protruded, a mouthpiece 30 having an insertion hole 30a into which the boss 11 is inserted, and a fiber reinforced resin which covers an outer side of the liner 10 and an outside surface of the mouthpiece 30. The mouthpiece 30 is fixed to the liner 10 by press-fitting of the boss 11 in the insertion hole 30a, and a pressurizing space PS for pressing the boss 11 to the mouthpiece 30 side with an internal pressure of the gas or the liquid is formed on an inner periphery of the boss 11.SELECTED DRAWING: Figure 2 |
