A turbine rotor is fixed to a turbine rotor, and a turbine stationary part corresponding to the outer peripheral part of the tip of the turbine rotor blade has a gap between the outer peripheral part of the tip of the turbine rotor blade and the stationary part. A steam turbine characterized in that a gap adjustment mechanism is provided. 2. The gap adjustment mechanism has an annular plate provided in a stationary part corresponding to the turbine rotor blade, an inner ring part of the annular plate covers the outer peripheral part of the tip of the turbine rotor blade, and the inner ring part of the annular plate covers the outer peripheral part of the tip of the turbine rotor blade. The steam turbine according to claim 1, wherein the steam turbine is configured to adjust the gap between the moving blade and the stationary part by moving the moving blade toward and away from the tip of the moving blade. 3. The inner ring of the annular plate is formed in a tapered shape corresponding to the outer periphery of the tip of the turbine rotor blade, and by moving this annular plate in the axial direction of the turbine rotor, the gap between the turbine rotor blade and the annular plate is adjusted. A steam turbine configured as described in claim 2 of the utility model registration claim. 4. A measurement probe is disposed in the inner annular portion of the annular plate, and the distance between the inner annular portion of the annular plate and the outer periphery of the tip of the turbine rotor blade is measured by the measurement probe. The steam turbine according to item 3. 5 The measurement probe and the driving source of the annular plate are connected through a computer, and this computer moves the annular plate based on the signal from the measurement probe to adjust the gap between the annular plate and the turbine rotor blade. The steam turbine according to claim 4 of the utility model registration claim, which optimizes.
