摘要： PROBLEM TO BE SOLVED: To provide a turbine partition plate capable of securely fixing a stationary blade and an inner ring by a simple configuration.
SOLUTION: A pressure supply channel a is formed of the outer peripheral face of the inner ring 14 on the upstream side in the direction of the flow of steam indicated by an arrow mark to a rising face 14ab. Consequently, steam pressure on the upstream side is transmitted along the pressure supply channel a and led between the outer peripheral face 14ac of a fitting part 14a and the bottom face 3bc of a fitting part 3b when operating a turbine to press the inner ring 14 in the direction of an inner periphery by this pressure. At this time, a rising face 14aa in the fitting part 14a slides while it is abutted on a rising face 3ba in the fitting part 3b, and the inner ring 14 moves to the upstream side in the direction of the flow of steam. As a result, a clearance between the rising faces 3ba and 14aa becomes zero, and a clearance between the rising faces 3bb and 14ab becomes zero. The fitting parts 3b and 14a are securely fitted, and the inner ring 14 is fixed to the stationary blade 3.
