    摘要： A sealing apparatus includes an annular lip member made of a resin material, and an annular spring member made of a metal material. The lip member includes a lip base portion, an outer-periphery-side lip, and an inner-periphery-side lip. The spring member includes: a spring base portion having an annular shape about an axis; an outer periphery pressing portion for pressing the outer-periphery-side lip; and an inner periphery pressing portion for pressing the inner-periphery-side lip. The spring member is accommodated in an accommodating groove. The outer periphery pressing portion includes a plurality of outer periphery pressing pieces, and the inner periphery pressing portion includes a plurality of inner periphery pressing pieces. The outer periphery pressing piece has a cutout extending along the axis without reaching a high-pressure-side edge of the outer periphery pressing piece, and the inner periphery pressing piece has a cutout extending along the axis without reaching a high-pressure-side edge of the inner periphery pressing piece.

    摘要： The sealing device includes: an outer peripheral ring 2000 that is in contact with a side wall surface of an annular groove 4100 at a low pressure side (L), and slides with respect to an inner peripheral surface of a shaft hole in a housing 5000 through which a shaft 4000 is inserted. An inner peripheral ring 3000 made of a rubber-like elastic body that is in contact with an inner peripheral surface of the outer peripheral ring 2000 and a groove bottom surface of the annular groove 4100, respectively. The outer peripheral ring 2000 is formed on its outer peripheral surface with a concave portion 2220 which extends from an end of a high pressure side (H) to a position which does not arrive at an end of a low pressure side, so as to introduce fluid thereinto from the high pressure side.
