PROBLEM TO BE SOLVED: To provide a segment joint which can weaken the inserting force of a male joint, and which prevents the male joint from coming off from a female joint. SOLUTION: The female joint 10 of a between-rings joint 1 comprises: a pair of rotatably-arranged circular cams 12A and 12B; a female-side tooth portion 13 in which a tooth surface is formed in the tangential direction of the outer peripheral portion of each of the circular cams 12; and a pushing protrusion 14 with a pushing surface, which adjoins the female-side tooth portion 13, and which is protruded from the outer periphery of each of the circular cams 12. The male joint 20 is provided with a plate-like insertion member 21 which is protruded from a male-side joint surface 20a of a segment 20A, which can be inserted between the circular cams 12, and in which a male-side tooth portion 22 capable of being meshed with the female-side tooth portion 13 is formed. When the plate-like insertion member 21 is inserted between the circular cams 12A and 12B, the female-side and male-side tooth portions 13 and 22 are meshed with each other.
