シール。[Claims for Utility Model Registration] (1) In an air seal for an air rotary joint that supplies compressed air from the outside to a pneumatic device through a rotating shaft, two rubber annular seals each having a lip portion that slides into contact with the rotating shaft are provided. The air seals are arranged at intervals in the axial direction, and a through hole is formed in the outer circumference of one of the air seals facing the interval, and the interval is communicated with an oil cooling chamber radially outward through the through hole. An air seal for an air rotary joint, characterized in that the sealed oil sealed between both air seals is cooled. (2) The outer periphery of the air seal in which the through hole is formed extends radially outward from the outer periphery of the other air seal, and a stepped fitting portion is provided to position the outer periphery of the other air seal in the axial direction. An air seal for an air rotary joint according to Claim 1 of the Utility Model Registration Claim.
