Provided is a shaft sealing apparatus (1), which includes a seal ring (11) that is installed in an annular space between a rotor (2) and a stator surrounding an outer circumference side of the rotor (2), that is formed in a divided structure from a movable seal ring (12) and a stationary seal ring (13) whose circumferential ends are adjacent to each other, and that is configured so that the movable seal ring (12) is biased toward a radial outer side thereof by an elastic body (28), a seal body (9) that is formed by stacking a plurality of thin seal pieces (10), which extend from the seal ring toward a radial inner side of the rotor, in a circumferential direction of the rotor, and a communicating part (34) that causes the low-pressure side region and the high-pressure side region to communicate with each other. |
