PROBLEM TO BE SOLVED: To provide a connected body having a superior seal characteristic capable of assuring a sealed state between two members having different coefficients of thermal expansion irrespective of temperature environment.SOLUTION: A connected body includes two connecting members 21, 22 having different coefficients of thermal expansion and an annular gasket 3 arranged between the two connecting members 21, 22. The connecting members 21, 22 are connected in a state in which they hold the gasket 3. The gasket 3 has a segment 31 to be contacted and a self-contact part 32 contacted with the segment 31 to be contacted without being contacted with the connecting members 21, 22 at a section including a central axis of the gasket 3. The segment 31 to be contacted is contacted with any one of the two connecting members 21, 22 at one side in a holding direction X of the gasket 3 and contacted with the self-contact part 32 at the other side. |
