PROBLEM TO BE SOLVED: To provide a joint which facilitates connection of two segments adjacent to each other in a circumferential direction, and prevents wobble of the segments after connection of the same. SOLUTION: The joint is formed of a male joint 2 arranged on a contact surface 17 of one of the segments 15 adjacent to each other, and a female joint 6 arranged on a contact surface 26 of the other segment 15. The male joint 2 has a fitting member 3, and the female joint 6 has a fitted member 7. Then, the fitting member 3 and the fitted member 7 are fitted to each other in a direction along the contact surfaces 17, 26, and therefore both the segments 15, 15 are connected together in one body. The contact surface 17 of the one segment 15 has a projection 18 and a recess 20 formed along the contact surface 17, on the other hand the contact surface 26 of the other segment 15 has a recess 27 and a projection 29 along the contact surface 26. Therefore, by fitting the projection 18 into the recess 27, and the recess 20 onto the projection 29, respectively, wobble of both the segments 15, 15 after connection of the same can be prevented.
