<p>PURPOSE:To aim at improvements in turbine efficiency by installing a seal plate, pressing a blade to another side wall with pressure, nippingly between a flange to which the blade is clamped and the side wall. CONSTITUTION:A seal plate 200 is installed nippingly between a flange 112 to which plural nozzle blades 111 are clamped and a side wall 121, and these nozzle blades 111 are pressed to another side wall 130 with pressure. With this constitution, a clearance between these blades 111 and the side wall 130 is reduced so narrow enough so that turbine efficiency is improvable.</p> |
