Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a connection structure for a flange pipe and a fluid device which can maintain a suitable sealing property almost without additional refastening and can improve assembling workability. SOLUTION: In the connection structure for both flange pipes 1, 2, a first seal end t1 is arranged on a first flange section 1B, and a second seal end t2 is arranged on a second flange section 2B. A circular groove 6 is formed at an outer diameter side of a fluid passage 4 on the first seal end t1, and a circular projection 8 press-fitted into the circular groove 6 is formed at an outer diameter side of the fluid passage 4 on the second seal end t2. The connection structure has a pulling means M for mutually pulling both of first and second flange sections 1B, 2B and maintaining the pulling situation of them. A fitting seal section 3 is formed by engaging the circular groove 6 of the first flange section 1B with the circular projection 8 of the second flange section 2B. COPYRIGHT: (C)2011,JPO&INPIT
