PROBLEM TO BE SOLVED: To provide a shaft sealing mechanism, capable of reducing the leakage amount of a gas from a high pressure side to a low pressure side and having superior abrasion resistance, and to provide a gas turbine having the shaft sealing mechanism. SOLUTION: In this shaft-sealing mechanism, a leaf seal 25 with a clearance adjustment for making a clearance at low pressure side 31 to be larger than a clearance at high pressure side 32, is applied as a gas pressure adjusting means for adjusting the gas pressure to be added to a lower face 29b higher than the gas pressure to be added to an upper face 29a at tan arbitrary position along the cross section of a thin plate 29. In this gas turbine, the constitution including the leaf seal 25 is adopted. |
