AXIAL SEAL STRUCTURE AND ROTATION MECHANISM PROVIDED WITH SAME

An axial seal structure includes a high-pressure-side regulating member (30) that regulates the flow of a fluid from a high pressure side to multiple thin sheet seal pieces (20) arranged with minute gaps from each other in the circumferential direction along the high pressure side of the multiple thin sheet seal pieces (20) and along an outer periphery of a rotating shaft (6). The high-pressure-side regulating member (30) has flexible multiple wires (35). Longitudinal directions of the multiple wires (35) are directed towards a direction having a radial component of the rotating shaft (6). Tips (35b) that are radial inner ends of the wires form free ends, and are brought into close proximity to or into contact with the outer peripheral surface of the rotating shaft (6). The wires (35) that are adjacent to each other in the circumferential direction come into contact with each other partially in the longitudinal directions.
