ール装置。 In a sealing device for a rotating machine that seals between an axial hole provided in a housing of a rotating machine and a rotating shaft passing through a coaxial hole by an oil film formed in that part, a cross-sectional shaped groove is formed in an annular groove formed in the axial hole. A first annular seal member is housed on the outer side of the annular case, and a second annular seal member is housed on the inner side of the annular case and contacts the outer side surface of the annular groove. A first annular protrusion is provided on the outer periphery side of the outer surface of the annular case, and a second annular protrusion that contacts the first annular seal member is provided on the inner periphery side of the inner surface of the annular case. A sealing device for a rotating machine, characterized in that a plurality of circular arc surfaces continuous in the circumferential direction are formed on the inner peripheral surface of the first annular seal member.
