Abstract

A primary technical goal of the present invention is to improve the durability and the seal performance of a cup gasket for a mechanical seal device which retains a seal ring. The mechanical seal device disposes a cup gasket made of a resilient rubber material between the mounting surface of the first seal ring and the step shoulder installation surface in which the cup gasket retains a support plate in an integral manner and the support face of the support plate facing opposite relative to and in approximately parallel with the mounting surface of the seal ring.
