とを特徴とするたわみ軸追従軸封装置。In a shaft sealing device in which a rotary ring fixed to a rotary shaft side is slidably pressed into contact with a fixed ring fixed to a housing side, and the internal fluid is sealed by the sliding surface of the rotary ring, a housing is attached around the fixed ring. An O-ring is interposed between the inner surface of the flange, which is slidably supported only in the axial direction, and the tapered outer periphery formed on the outer periphery of the fixed ring, and the fixed ring and/or the housing are mounted on the back surface of the O-ring. A backup ring made of an annular elastic body inserted and supported on one side is provided, and the fixed ring is elastically biased inward in the axial direction, and is interposed between the rotating ring and a spring bearing seat inserted externally on the rotating shaft. A deflection shaft following shaft sealing device that maintains appropriate sliding surface pressure and angle in accordance with the nature of the coil spring installed.
