PROBLEM TO BE SOLVED: To provide a segment joining structure of high work efficiency while forming a joining protrusion part of a male-type joint into simple structure. SOLUTION: This joining structure 1 is structured to project a joining recessed part 3 of a female-type joint 4 originally with high structural rigidity from a joint face 2a of a segment 2 and to retract the joining protrusion part 6 of the male-type joint 7 from the joint face 2a. The joining structure 1 forms the joining protrusion part 6 of the male-type joint 7 into simple structure by putting a spacer 9 of an elastic body between a case part 8 and a supporting ring part 10 forming the double pipe structure of the joining recessed part 3 of the female-type joint 4, and absorbing "looseness" in construction only on the female-type joint 4 side.
