ABSTRACT:
A sealing apparatus capable of increasing a grease resistance property, wherein the tip of a sealing lip is formed so that an inner side contact angle α is equal to an open-air side contact angle β (α=β), that is, formed in a triangular shape to prevent grease inside the apparatus from leaking so as to increase the grease resistance property, and since the extending direction of the sealing lip is set at a middle of an inner side and an open-air side, a trouble such as the inversion of the sealing lip due to the occurrence of an inner pressure does not occur.
