Axial seal structure and rotation mechanism provided with same
An axial seal structure includes a high-pressure-side regulating member configured to regulate the flow of a fluid from a high-pressure-side region to multiple thin sheet seal pieces arranged with a minute gap between each of the multiple thin sheet seal pieces in a circumferential direction along a high pressure side of the multiple thin sheet seal pieces and along an outer peripheral surface of a rotating shaft. The high-pressure-side regulating member has multiple wires that are flexible. Respective longitudinal directions of the multiple wires are directed towards a direction having a radial component of the rotating shaft. Tips that are radial inner ends of the wires form free ends, and are in close proximity to or in contact with the outer peripheral surface of the rotating shaft. The wires that are adjacent to each other in the circumferential direction come into contact with each other partially in the longitudinal directions.
