<P>PROBLEM TO BE SOLVED: To realize a seal structure capable of improving seal performance while suppressing plastic deformation of seal rings in a seal structure for inserting the seal rings onto a rotating shaft to be inserted into a bush. <P>SOLUTION: The seal rings 32 are fit onto the rotating shaft 29 via abutment joints 32b and they are laminated in an axial direction. A protruding part 32c is formed on each of the seal rings, and by fitting the protruding part 32c on each abutment joint 32b, relative rotation of each seal ring 32 around the rotating shaft 29 is regulated in a state with the abutment joints 32b arranged in different positions in a circumferential direction of the rotating shaft 29. <P>COPYRIGHT: (C)2008,JPO&INPIT |
