PROBLEM TO BE SOLVED: To easily obtain a target of completion of appropriate pumping by visually judging whether or not the internal pressure in a pressurized fuel container reaches a presciribed pressure condition during the pumping. SOLUTION: A pressurized fuel container is provided with a cap body 4 having a through hole, a cylindrical body provided on an inner side of the cap body 4, a rodshaped indicator 12 which is fitted to a piston 15 slidably inserted in the cylindrical body and capable of being advanced/retracted outward of the cap body 4 through the through hole, a closing body 19 which closes the other end part of the cylindrical body 11 to communicate the inside of the cylindrical body 11 with the outside thereof, a sealing means 17 to cover the space between the piston 15 and the cylindrical body 11 in a slidable manner in the cylindrical body, and a pressing means 23 which is arranged inside the cylindrical body 11 and presses the piston 15 toward the closing body 19. |
