Claims

[Scope of utility model registration request]

In a mechanical seal in which a sealed end surface is formed by bringing a seat ring and a driven ring, which have mutually different opposing surface widths, into opposing contact with each other, one of the seat ring and the driven ring is made eccentric from the center of the rotating shaft, and A mechanical seal characterized in that the mechanical seal is configured to cause relative movement in the radial direction between the seat ring and the driven ring at the sealed end surface.
