<P>PROBLEM TO BE SOLVED: To provide a joint structure having a high flexural capacity against force on a joint in its inserting/removing direction for enabling firm connection between segments. <P>SOLUTION: The joint structure includes a male side joint member 3 having a male side supporting plate 6 whose surface is protruded to the further side in a ring peripheral direction than a butting part end face 2a of one segment toward a ring axial direction, and a female side joint member 5 having a female side supporting plate 20 which is exposed into a recessed portion 4 opened to a butting part end face 2b of the other segment at a position where it is opposed to the male side supporting plate 6. The male side joint member 3 is inserted into the recessed portion 4 and both segments are moved relatively in the ring axial direction for putting a male side engagement fitting 7 in engagement with a female side engagement fitting 21 to butt the segments. The male side engagement fitting 7 and the female side engagement fitting 21 are integrally formed into a U-shape with their engaging parts engaging each other to restrict the movement of the male side joint member 3 in its removing direction and their flexural reinforcement pars extending from the edges of the engaging parts toward the male side joint member in its inserting/removing direction. <P>COPYRIGHT: (C)2013,JPO&INPIT |
