PROBLEM TO BE SOLVED: To provide a joint and a simple joint installation structure capable of facilitating installation of the joint, downsizing the same and sufficiently and reliably holding an inner cylinder member.SOLUTION: A joint 1 comprises: an inner cylinder member 2; and an outer cylinder member 3 which forms an insertion space 11 to insert a pipe body 8 with respect to the inner cylinder member 2. The inner cylinder member 2 has: an inner cylinder small diameter section 22 which is inserted inside a second storage section 72 of an installation storage section 70 of an installation member 7; and an inner cylinder large diameter section 21 which has an outer diameter larger than that of the inner cylinder small diameter section 22 and is inserted inside a first storage section 71 of the installation storage section 70. The outer cylinder member 3 has an outer cylinder insertion section 31 which is arranged outside the inner cylinder small diameter section 22 and inserted inside the second storage section 72 together with the inner cylinder small diameter section 22. The outer diameter of the inner cylinder large diameter section 21 is smaller than that of the outer cylinder insertion section 31. A retaining member 41 to prevent the outer cylinder insertion section 31 from being pulled out is arranged between the outer cylinder insertion section 31 and the second storage section 72.SELECTED DRAWING: Figure 1 |
