AXIAL SEAL STRUCTURE AND ROTATION MECHANISM PROⅥDED WITH SAME

摘要

This shaft seal mechanism follows the high pressure side of a large number of thin plate seal pieces 20 arranged with a small space in the circumferential direction and moves along the periphery of the rotary shaft 6 from a high pressure side to a large number of thin plate seal pieces 20, And a high-pressure-side regulating member (30) for regulating the flow of the high-pressure-side regulating member (30). The high-pressure-side regulating member 30 has a plurality of flexible wires 35. The plurality of wire rods 35 are oriented in the longitudinal direction in a direction having a radial component of the rotary shaft 6. The distal end portion 35b, which is the inner end in the radial direction of the wire rod, forms a free end and is in close proximity to or in contact with the outer peripheral surface of the rotary shaft 6. [ The wire members 35 adjacent to each other in the circumferential direction are in contact with each other in a part of the longitudinal direction thereof.
