。 A rotating ring attached to the rotating shaft side is slid into contact with a fixed ring fixed to the housing side of the machine body through which the rotating shaft is inserted, and the rotating ring is pressed against the fixed ring side to seal the sealing liquid. In the mechanical seal, the fixed ring has a sliding surface on its outer periphery, a bottom surface portion opening in a substantially tangential direction contrary to the rotational direction of the rotating ring, and a side surface portion facing the rotational direction of the rotating ring. A plurality of the formed notched grooves are cut in the shape of an impeller along the circumferential direction, and each of these notched grooves is provided with a communicating hole facing the outer circumferential surface of the fixed ring in the radial direction. mechanical seal.
