グメントシール。 In a segment seal in which arc-shaped sliding members divided into multiple pieces in the circumferential direction are connected in an annular manner and fitted to the outer periphery of the shaft side, the inner diameter sliding surface of each sliding member is opened in the high pressure side axial direction. 1. A non-contact type segment seal characterized in that a tapered stepped portion having a wedge-shaped tapered surface is configured to become gradually shallower in the rotating direction of a shaft, thereby adding radial buoyancy to the segment seal.
