摘要: Primary objective of the present invention is to provide a seal device for effecting a seal against a high temperature, high pressure fluid and to maintain seal surfaces thereof in a sealing contact relation with mount surfaces regardless of the displacement of the mount surfaces. The seal device is comprised of a first seal portion (2), a second seal portion (12), a joint base (3), a first seal face (2C1) and a second seal face (12C1), wherein the first seal portion (2) has a first elastic portion (2C) at one side of a first bight portion (2B) and a second elastic portion (2A) at the other side of the first bight portion (2B), wherein the second seal portion (12) has a first symmetrical elastic portion (12C) at one side of a second bight portion (12B) and a second symmetrical elastic portion (12A) at the other side of the second bight portion (12B), wherein the joint base (3) is deflected and joining the second elastic portion (2A) of the first seal portion (2) and the second symmetrical elastic portion (12A) of the second seal portion (12) such that the second elastic portion (2A) and the second symmetrical elastic portion (12A) are aligned in parallel with one another, wherein the first seal face (2C1) is disposed on a first outmost circumferential surface of the first elastic portion (2C), wherein the second seal face (12C1) is disposed on a second outmost circumferential surface of the first symmetrical elastic portion (12C), wherein a side surface (2A1) of the second elastic portion (2A) and a side surface (12A1) of the second symmetrical elastic portion (12A) are in a contact relation or in a proximity contact relation with one another in an opposing manner at the joint base (3).
