とを特徴とする軸封装置。 A tapered, non-contact threaded seal that gradually expands in diameter toward the inside of the machine is installed between the opposing circumferential surfaces of the rotating ring that is externally fitted onto the shaft and the fixed ring that is fitted into the inner periphery of the shaft hole of the body. A seal ring is provided at one end opening of the threaded seal, and is elastically supported by a retainer connected to the one ring, and contacts and separates from the other ring due to a pressure difference between the inside and outside, and further includes a seal ring on the body side. A shaft characterized in that the inner diameter portion of the thrust bearing fixed to the shaft is provided with a bearing mechanism that slidably and rotatably engages between the opposing end surfaces of the rotating ring and a collar fixed to one end of the rotating ring. Sealing device.
