PURPOSE:To reduce both thermal stress and gas leakage at a stator blade, by tightly jointing an upper plate which forms the stator blade in a ring shape, while the lower plate is jointed softly so as to allow relative displacement. CONSTITUTION:A pair of an upper plate 1 and lower plate 3 is set for one stator blade 2. The adjoining upper plate 1 is bolted 8 at its flange 7 and the adjoining lower plate 3 is jointed with a light elastic deformation by inserting an elastic pin 9 into a triangular slot. Thermal stress of the stator blade can be reduced thereby and gas leakage through the side plates can be also decreased. |
