Abstract
A bent tube 10 includes joint rings 11 spacedly arranged, side by side, in a row and a connection mechanism 20 which is bridgingly disposed between one of the adjacent joint rings 11 and the other. The connecting mechanism 20 has a pair of hinge members 21, 22 which are rotatably connected around a rivet 23 (rotation axis). The hinge 21 is fixed to a groove 11c (hinge attaching portion) formed in one of the adjacent joint rings 11 by soldering, and the hinge member 22 is fixed to a groove 11c formed in the other joint ring 11 by soldering. By this, caulking operation, which is necessary for connecting the joint rings, can be performed easily.
