Abstract:
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.

Claim (Index 1):
A sealing apparatus for sealing an annular space formed between two members which are movable relative to each other, the sealing apparatus comprising:\n a lip member which is a member made of a resin material and which has an annular shape about an axis; and a spring member which is a member made of a metal material and which has an annular shape about the axis, wherein the lip member includes: a lip base portion which is a portion having an annular shape about the axis; an outer-periphery-side lip which is an annular lip extending toward one side from an outer periphery side of an end portion of the lip base portion on the one side in a direction of the axis; and an inner-periphery-side lip which is an annular lip extending toward the one side from an inner periphery side of the end portion of the lip base portion on the one side, and an accommodating groove which is an annular groove recessed toward an other side from the one side in the direction of the axis is formed in the lip member, the spring member is accommodated in the accommodating groove, and the spring member includes: a spring base portion which is a portion having an endless annular shape about the axis; an outer periphery pressing portion for pressing the outer-periphery-side lip from the inner periphery side; and an inner periphery pressing portion for pressing the inner-periphery-side lip from the outer periphery side, the outer periphery pressing portion is a portion extending such that the portion inclines ward the outer periphery side from an end portion of the spring base portion on the outer periphery side toward the one side, and the outer periphery pressing portion includes a plurality of outer periphery pressing pieces which come into contact with the outer-periphery-side lip from the inner periphery side, the inner periphery pressing portion is a portion extending such that the portion inclines toward the inner periphery side from an end portion of the spring base portion on the inner periphery side toward the one side, and the inner periphery pressing portion includes a plurality of inner periphery pressing pieces which come into contact with the inner-periphery-side lip from the outer periphery side, the outer periphery pressing piece has a cutout extending along the axis without reaching an edge of the outer periphery pressing piece on the one side, and the inner periphery pressing piece has a cutout extending along the axis without reaching an edge of the inner periphery pressing piece on the one side.
