する、請求項１に記載するベローズシール。[Claims for Utility Model Registration] (1) A bellows seal consisting of a stationary sealing ring held in a casing and a rotating side assembly having a unit structure held on a rotating shaft, wherein the rotating side assembly is connected to the stationary sealing ring. A rotary sealing ring that can be slidably contacted, an assembly fixed ring fixed to the rotating shaft, a retaining ring that engages and holds the rotary sealing ring in a manner that prevents relative rotation, and is interposed between the rotary sealing ring and the assembly fixed ring. A bellows made of fluororesin whose front end is tightly fitted to the rotary sealing ring and the retaining ring is connected to the assembly fixed ring via a connecting bolt extending in the axial direction, so that the retaining ring cannot be rotated relative to the A bellows fixing ring that engages and holds the bellows relatively movably in the axial direction and tightly fixes the rear end of the bellows to the rotating shaft, an assembly fixing ring, and a retaining ring to statically seal the rotating sealing ring. It is characterized by comprising a spring that presses the ring, and configured such that the assembly fixed ring can be temporarily fixed to the bellows fixed ring with a connecting bolt while the bellows and the spring are held at a free length. bellows seal. (2) The bellows fixing ring includes an annular body connected to the assembly fixing ring via a connecting bolt, and a bellows fixing ring that is fitted inside the main body and externally engaged with the rear end of the bellows. Consisting of a split annular tightening body having a tapered outer peripheral surface whose diameter gradually increases, the tightening body is configured such that the diameter of the tightening body is reduced by tightening the main body in the direction of the assembly fixing ring using a connecting bolt. The bellows seal according to claim 1, characterized in that:
