PROBLEM TO BE SOLVED: To provide a sealing device which comprises a combination of a slinger and a lip member, and the sealability of which can be enhanced by suppressing a decrease in repulsive force of an end face lip due to a permanent set in fatigue.SOLUTION: The sealing device has a slinger mounted on one of two relatively rotating members and a lip member mounted on the other member. The slinger has a cylindrical part, fitted to the one member, and a flange part extending in a radial direction, in one body, and the lip member has an end face lip coming into slidable contact with the flange part. A back-up lip which suppresses a decrease in repulsive force of the end face lip due to a permanent set in fatigue is provided in contact with a back of the end face lip. |
