(EN)

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.
