PROBLEM TO BE SOLVED: To perform construction in a short time when communicatively connecting two piping ducts over two faces to be attached which intersect with each other, in a duct joint which is used in communicative connection in a state that the two piping ducts are twisted substantially at 90° with respect to each other.SOLUTION: In a joint main body 5, a first connecting port 53 having a substantially-rectangular cross section cylindrical shape corresponding to a connecting port of a first piping duct, and a second connecting port 54 having a substantially-rectangular cross section cylindrical shaft corresponding to a connecting port of a second piping duct are connected to each other in a prescribed connecting direction in a state that they are twisted substantially at 90° with respect to each other. The joint main body 5 has overlapping parts 55 which are overlapped on each other when viewed from a direction orthogonal to the prescribed connecting direction between a part of the first connecting port 53 and a part pf the second connecting port 54. Internal corners 56 are formed at the overlapping parts 55. |
