摘要： A structure for connection between a metal bellows tube (A) and a metal tube (B) of a different material from the bellows tube. A connection section of the bellows tube has a straight tube section (1) in the bellows tube, a nipple (2), a bellows tube reinforcing section (3), and a fastening collar (4), and they are fitted and secured to each other in that order from the inside of the tube. The nipple has a base section (2-1) joined to the reinforcing section and a connection end section (2-2) extending to the metal tube side. The fastening collar has a small diameter section (4-1) on the metal tube side and a large diameter section (4-2) on the bellows tube side. A connection section of the metal tube is constructed from a connection end section (6) of the metal tube and a sleeve (7) secured to the outer side of the connection section. The sleeve (7) has a base section (7-1) joined to the connection section and a fitting end section (7-2) extending to the bellows tube side. The fitting end section of the sleeve is fitted on the small diameter section of the fastening collar, and the outer surface of the connection end section of the nipple and the inner surface of the connection end section of the metal tube are bonded and fixed by heat curing resin, with end surfaces of the bellows tube reinforcing section and of the fastening collar and an end surface of the metal tube made to be in contact or to be close to each other.
