PURPOSE:To obtain a propulsive support structure to be easily disassembled, having excellent processability, by a method in which a propulsive support part is detachably set on one connecting frame separated from connecting frames facing each other and a regulative screw to be coupled with the free end of the separated propulsive support part is provided to the other connecting frame. CONSTITUTION:Connecting frames 16 set separately along the circumferential direction on the end faces of segment rings facing each other are of an almost U-shaped cross section along the axial direction of the segment ring 10. A propulsive support part 22 is set between the wall parts of the connecting frames facing each other separately. The part 22 is fixed to the wall part 16b of one connecting frame 16 by using one flange and by using fixing bolt 24 for example. A regulative screw 28 is attached to the wall part 16b of the other connecting frame 16 facing the part 22 through a space 26. By turning the screw 28 in the axial line direction, it is coupled with the flange of the part 22 or is separated from it. |
