。 A non-rotating annular body that is circumferentially divided into a plurality of segments and bound together in the circumferential direction with an extension spring is housed in an annular housing formed on the inner periphery of the housing. In a float type segment seal in which one end surface is in close contact with the end surface of the housing and the inner circumferential surface of the annular body faces the outer circumferential surface of the rotating body through a minute clearance, the radius of curvature of the inner circumferential surface of each segment is The diameter is slightly smaller than the radius of the outer circumferential surface of the rotating body, and the inner circumferential surface of each segment disappears when the inner circumferential surface of each segment becomes a cylindrical surface concentric with the outer circumferential surface of the rotating body due to wear. A float-type segment seal that is characterized by the formation of a small gap.
