A SEALING STRUCTURE FOR A COMPRESSOR SHAFT INCLUDES A SLEEVE MEMBER MOUNTED TO THE SHAFT AND A FLANGE EXTENDS RADIALLY INWARD FROM AN INNER PERIPHERY OF THE SLEEVE MEMBER. A FIRST BOWL-SHAPED SEAL HAS A NARROW PORTION MOUNTED TO THE SHAFT, AND A WIDER PORTION ENGAGED WITH THE FLANGE. A SECOND BOWL-SHAPED SEAL IS MOUNTED TO THE SHAFT AND IS ENGAGED WITH AN INNER SURFACE OF THE WIDER PORTION OF FIRST BOWL-SHAPED SEAL. A POSITIONING MEMBER COMPRESSES THE SECOND BOWL-SHAPED SEAL TOWARD THE FIRST BOWL-SHAPED SEAL SO THAT THE FIRST BOWL-SHAPED SEAL AND SECOND BOWL-SHAPED SEAL ARE SECURELY POSITIONED BETWEEN THE FLANGE OF THE SLEEVE MEMBER AND THE POSITIONING MEMBER.
