<P>PROBLEM TO BE SOLVED: To provide a shaft sealing mechanism adopting a leaf seal capable of suppressing leak amount of working fluid even when relative eccentricity of a rotational shaft is excessively generated. <P>SOLUTION: A high-pressure side side plate 24 that is a component of the leaf seal 20 is constituted by stacking a second annular plate 32 and a first annular plate 31 in sequence toward each thin plate 21 of a thin plate group. The inner diameter of the first annular plate 31 is larger than that of the second annular plate 32, and the first annular plate 31 is brought into contact with one side that is the high-pressure side of the each thin plate 21. In an inner peripheral edge part of the second annular plate 32, a projection 38 comes into contact with the one side that is the high-pressure side of the each thin plate 21 is provided. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
