Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a sealing structure having a high degree of freedom in design which is superior in air tightness for securing durability and reliability on pressure increasing/reducing stress as an issue on the sealing structure of an independent elastomer seal, and which is suitable to a fuel cell high pressure hydrogen gas container for suppressing the capacity of the sealing structure, particularly, the width thereof. SOLUTION: The cylindrical fixed flange structure is provided for a high pressure gas container to be filled with high pressure gas. It comprises a high-pressure-side primary seal zone having a metal touch seal, and an atmosphere-side secondary seal zone having the elastomer seal. The high-pressure-side primary seal zone and the atmosphere-side secondary seal zone are arranged on the front and rear sides of the high pressure gas container in the cylindrical direction, respectively.
