Abstract:
A sealing device according to some embodiments comprises: a sealing member that is disposed between a rotating member of a rotating machine and a stationary member disposed on the outer side of the rotating member in the radial direction of the rotating member, and that creates a seal between the rotating member and the stationary member; and a biasing member that biases the sealing member toward the radially outer side. The sealing member has a base extending in the circumferential direction of the rotating member, a rib that extends in the circumferential direction and protrudes outward in the radial direction from the base, and a seal fin that extends in the circumferential direction and protrudes inward in the radial direction of the rotating member from the base.
