Claims

[Scope of utility model registration request]

A seal ring that is divided into a plurality of parts in the circumferential direction is tightened in the inner radial direction by an extension spring that fits on the outer periphery of the seal ring so that it slides closely against the outer peripheral surface on the shaft side, and a spring that fixes the seal ring to the housing. In a segment seal formed by pressing axially against the radial surface of the housing by a compression spring whose rear end is supported by a retainer, an annular sliding body is provided on the radial surface of the housing facing the seal ring. A segment seal characterized by being airtightly and removably fixed.
