エア回転継手のシール装置。 In an air rotary joint that supplies compressed air from the outside to pneumatic equipment through a rotating shaft, a substantially annular cover is provided that extends for a predetermined length in the axial direction so as to surround the radially outer side of the rotating shaft. An air passage is formed to introduce compressed air from the outside, and a mechanical seal mechanism is provided to seal the compressed air flowing from the air passage to the air inlet of the rotating shaft, and the cover is rotated axially outward of the mechanical seal mechanism. A lubricating oil system that includes a bearing that is supported on the shaft, a lip seal type oil seal that presses against the outer peripheral surface of the rotating shaft on the outside of the bearing in the axial direction, and the lubricating oil that flows into the space between this oil seal and the mechanical seal. A sealing device for an air rotary joint, comprising a connecting member forming a passage and connecting the cover to an external fixing member.
