To provide a joint structure which can prevent a gasket from being excessively fastened while achieving simplification of a joint member, and to provide an assembly method of the joint structure.SOLUTION: A joint structure 1 includes: a first joint member 2; a second joint member 4; a gasket 6 disposed between the first joint member 2 and the second joint member 4; and a retainer 7 which is attached to the outer periphery side of the first joint member 2 and holds the gasket 6. A butted end surface 24 of the first joint member 2 is provided with: a first contact area 25 with which the retainer 7 contacts; and a first projection 26 pressed to one end surface of the gasket 6. A butted end surface 43 of the second joint member 4 is provided with: a second contact area 44 with which the retainer 7 contacts; and a second projection 45 pressed to the other end surface of the gasket 6.SELECTED DRAWING: Figure 1 【課題】継手部材の簡素化を図りながらガスケットへの過剰締め付けを防止することができる継手構造及び継手構造の組み付け方法を提供する。【解決手段】継手構造１は、第１継手部材２と、第２継手部材４と、第１継手部材２と第２継手部材４との間に介装されるガスケット６と、第１継手部材２の外周側に取り付けられ、ガスケット６を保持するリテーナ７と、を備える。第１継手部材２の突き合わせ端面２４には、リテーナ７が当接する第１当接領域２５と、ガスケット６の一方の端面に押し付けられる第１突起２６と、が設けられ、第２継手部材４の突き合わせ端面４３には、リテーナ７が当接する第２当接領域４４と、ガスケット６の他方の端面に押し付けられる第２突起４５と、が設けられる。【選択図】図１
