Sealing device and rotating machine

A sealing device comprising:

• a sealing member provided between a rotating part and a stationary part of a rotating machine in a radial direction of the rotating machine;
• a holding member that is at least partially accommodated in a groove provided in the stationary part to extend along a circumferential direction and that supports the sealing member to be movable along the radial direction;
• and
• a plurality of first biasing members that are each configured to be accommodated in the holding member and to bias the sealing member along a vertical direction with respect to the holding member and that are provided at a plurality of positions that are different from each other in the circumferential direction, respectively,
• wherein the plurality of first biasing members are each configured to generate a biasing force in directions parallel to each other,
• wherein the holding member includes
• a base part that is accommodated in the groove, and
• a protrusion part that protrudes radially inward from the base part, and
• the sealing member has a sliding surface that is adjacent to the protrusion part in an axial direction and that is slidable relative to the protrusion part.
