Next, the operation of the embodiment of the joint structure of the present invention having the above-described configuration will be described. First, in order to change the joint structure from the open state shown in FIG. 2 to the connected state shown in FIG. The fluid enters the annular space defined by the holding member 2, the outer bellows 3 and the inner bellows 4,
The bellows 3 and 4 are extended toward the tubular member 14 side. Therefore, the movable holding member 2 also moves in the same direction, and the packing 12 embedded therein comes into contact with the flange 14a of the tubular member 14. When moving in this way, the joint tube 8 attached to the movable holding member 2
Since the movable holding member 2 is guided by the rollers 7 of the outer cylinder 6 attached to the fixed holding member 1, the movable holding member 2 can move smoothly without shaking as described above.
When the gasket 12 of the movable holding member 2 comes into contact with the flange 14a of the tubular member 14, the stopper 10 is rotated and the engaging protrusion 9 is pressed down.
2 is crimped to the flange 14a, and the tubular member 14,
15 are connected in a sealed manner by the joint structure of the present invention.
