Abstract:
PROBLEM TO BE SOLVED: To provide a seal structure of a high pressure container capable of maintaining perfect sealing without recharging gas over a long period, and capable of preventing a lid from being pushed out at a mouthpiece part by pressure for the atmosphere side, even in a case where a high pressure state continues.SOLUTION: In a seal structure configured to insert a lid body 3 into a metal cylinder 2 to perform sealing, a tapered female screw 2c and a parallel female screw 2b are engraved along an axis direction of the cylinder; on an outer peripheral surface of the lid body 3, a tapered male screw 3e is engraved, the tapered male screw screwed into the tapered female screw 2c to form a metal touch seal; and apart from the lid body 3 an axial force imparting member 4 is provided with a parallel male screw 4b engraved, the parallel male screw screwed into the parallel female screw 2b of the cylinder 2 to generate axial force larger than the lid body 3 between the parallel male screw and the cylinder 2.SELECTED DRAWING: Figure 1
