部と、このリツプ部を前記回転部材側に付勢する
スプリングと、を有する２個のシール装置を所定
間隔隔てて設け、両シール装置によつて形成され
た通路を介して前記固定部材に設けた流路と前記
回転部材に設けた流路とを連通した流体用ロータ
リージヨイントにおいて、前記固定部の少なくと
も一部又は前記スプリングを、所定温度より高く
なつたときに少なくとも一部が変形して前記リツ

造としたことを特徴とするシール装置。 a fixed part interposed between a fixed member and a rotating member and supported by the fixed member; a lip part provided continuously with the fixed part and in contact with the rotating member; and a lip part connected to the rotating member. two sealing devices having a spring biased toward the member side are provided at a predetermined interval, and a flow path provided in the fixed member and a sealing device provided in the rotating member are provided through a passage formed by both the sealing devices. In a fluid rotary joint that communicates with a flow path, at least a portion of the fixed portion or the spring is deformed when the temperature rises above a predetermined temperature, and the lip portion is attached to the rotating member. A sealing device characterized by having a variable structure that weakens the force applied.
