するテーパ面としたことを特徴とする軸封装置。 The lip seal is made up of an annular metal case that is hermetically fitted to the inner periphery of the shaft hole of the equipment housing, and an annular resin lip member whose outer diameter is hermetically fixed to the case. In a shaft sealing device configured to have an inner diameter portion of the lip member that protrudes in a curved or bent manner and come into sliding contact with the outer peripheral surface of the rotating shaft to prevent leakage of the sealing fluid, the rotating member that comes into sliding contact with the lip member. A shaft sealing device characterized in that the outer circumferential surface of the shaft is a tapered surface inclined at an appropriate angle so that the axial sealing fluid side has a larger diameter.
