PURPOSE:To substantially assure the heat resistance of a device under flow conditions of high-temp. fluid by forming inside and outside connecting bodies in such a manner that said bodies can be expanded and contracted by the bellows connected to the inside surface and integrally forming the two connecting bodies via a sliding member. CONSTITUTION:The heat resistant inside bellows 8 formed by laminating rubber, etc., via a heat radiating material 6 is airtightly connected to the inside of the inside connecting body 2. The outside bellows 21 is similarly connected to the inside of the outside connecting body 3. A heat insulating material 9 is circumferentially provided to the inside peripheral side of the bellows 8 of the inside connecting body 2 and a heat insulating material 11 is internally provided to a sleeve 10 fixed to the other end side. The sleeve 10 is slid axially along a guide cylinder 12 by a sliding bar 13. Sealing materials 16, 17 are fixed to the flange 4 surface of the inside connecting body 2 and the two connecting bodies 2, 3 are relatively moved in contact with a flange 18 in common use for sliding the outside connecting body 3. The temp. to be transmitted to the outside of the high-temp. fluid flowing in the bellows devices 2, 3 is thereby decreased.
