Claims

[Scope of utility model registration request]

A mechanical mechanical device comprising a driven ring that can move in the axial direction as the sealed end faces wear, and a seat ring that does not move, the driven ring and the seat ring being in close contact with each other and having sealed end faces that rotate relative to each other approximately perpendicular to the axis. In the seal, there is a groove formed concentrically with respect to the rotating shaft on the sealed end surface on the driven ring side, a plurality of radial grooves opening toward the outer circumference from this concentric groove, and a forward rotation on the sealed end surface remaining on the outer circumferential side. A mechanical seal characterized by having a surface tilted in the direction of rotation and a surface tilted in the reverse rotation direction.
