とを特徴とするロータリジヨイントシール。 A sealing mechanism of a joint that transfers fluid flowing through the axis of a rotating shaft to a pipe in a direction perpendicular to the axis includes a pair of seal rings movable in the axial direction and having an annular protrusion on the outer surface in the axial direction; It consists of a casing that has an opening communicating with the pipe line and is arranged to surround the pair of seal rings, and an annular spring that is interposed between the pair of seal rings and is compressively deformed in the axial direction, and the annular projection is caused by the annular spring to compress and deform in the axial direction. A rotary joint seal characterized in that an end face of the rotary joint seal is pressed against the inner surface of the casing to form a sealing surface.
