装置。 The periphery of the rotating shaft inserted into the casing is sealed with a pair of sealing rings consisting of a fixed ring fixed to the casing side and a rotating ring fixed to the rotating shaft side, which face each other in the axial direction. Each of these sealing rings is formed by a retainer, a face plate attached to the retainer via an O-ring and having a sealing surface tapered in the radial direction, and a holder for fastening and holding the face plate to the retainer. In the assembled non-contact type shaft sealing device, both peripheral edges of the inner and outer diameter parts of the face plate are fastened and held by the holder, and a gap is formed between the retainer and the face plate, which are attached via the O-ring. A non-contact type shaft sealing device that enables close contact without causing.
