ABSTRACT:
A sealing device dispossed between two members which are relatively rotatable, such as rotation shaft and housing of machinery, includes a first seal ring provided with a resin seal lip being disposed in an axial direction of one of the members to be sealed and having a sealing surface and a second seal ring provided with an elastic rubber seal lip disposed in an axial direction of one of the members to be sealed, the rubber seal lip being provided with a sealing surface closely contacting the sealing surface of the resin seal lip. The first and second seal rings are secured by a securing means. The securing device for securing the first and second seal rings is composed of an annular sealing recess formed on another surface of the resin seal lip opposed to the sealing surface thereof and a sealing projection formed on the sealing surface of the rubber seal lip of the second seal ring. The securing device may be composed of a bonding agent disposed between the end surface of a flanged portion of the first seal ring and the flanged portion of the second seal ring. The securing device is formed at the valcanization treatment of the sealing device in a mold.
