PROBLEM TO BE SOLVED: To provide a connection joint which can be aligned at a low cost and whose shearing stress can be reinforced, and to provide an alignment member and a segment equipped with the connection joint.SOLUTION: The connection joint includes a male member 10 which is arranged on one of connection faces 1a, 1b of segments 1, 1, a female member 20 which is arranged on the other and into which the male member 10 can be inserted, and an alignment member 30 including a through-hole part 31 having an inner diameter allowing the movement relative to a trunk part 11 of the male member 10 in the state of being passed through the trunk part 11, and a locked face part 33 having an outer peripheral face shaped to be locked to the inner peripheral face in the middle of an insertion passage when the male member 10 is inserted into the female member 20. The alignment member is formed and located so as to be passed through the trunk part 11 in the state before the male member 10 is inserted into the female member 20 and to contact the inner peripheral face in the middle of the insertion passage earlier than an engaging part 13 when the male member 10 is inserted into the female member 20. |
