There is provided a shaft sealing mechanism in which, even in a case where eccentricity occurs in a parent machine, flutter behavior of the sheets can be reliably prevented, the sheets can be prevented from failing due to fatigue, and also a long life and reliability of the shaft sealing mechanism can be improved. In a shaft sealing mechanism which prevents fluid from flowing in an axial direction of a rotor through an annular gap between the rotor and a stator, there are provided a high pressure side plate positioned on a high pressure side region of a plurality of sheets, and a low pressure side plate positioned on a low pressure side region of a plurality of sheets, and the construction is such that in a state in which the plurality of sheets is fixed on the stator side, and when under gas pressure, the parts make contact with each other.
