    • PROBLEM TO BE SOLVED: To provide a sealing structure of a pressure vessel preventing a reduction in a sealing function when a high pressure is loaded to the pressure vessel. SOLUTION: The sealing structure of the pressure vessel 1 comprises a resin liner 2 storing gas or a liquid, a fiber reinforced resin layer 3 reinforcing the outer surface of the resin liner 2, and a metal mouthpiece part 4 protruded on the outer surface of the fiber reinforced resin layer 3 to be a filling/discharging port. In the resin liner, a tubular filling/discharging part 22 with a through-hole 24, which is protruded outward from the inside of the pressure vessel, is formed. On the outer peripheral surface of the filling/discharging part, connection structures 23, 43 mutually connected with the inner peripheral surface of the mouthpiece part, are formed. In the through-hole 24 of the filling/discharging part, a tubular member 100 made by using a material with strength higher than that of the resin liner, is inserted and fitted. When a tubular valve 60 for filling/discharging the gas or liquid is inserted in a valve insertion hole 102 arranged in the tubular member through the mouthpiece part, a seal member 80 is interposed between the outer periphery 61 of the valve and the inner periphery of the valve insertion hole.
