ルシール。[Claims for Utility Model Registration] A fixed ring fixed to the housing side of the machine body, and a rotating shaft inserted into the housing of the machine body so as to be attached to the rotating shaft side so as to be slid elastically in contact with the fixed ring. In a mechanical seal equipped with a rotating ring, an annular groove is formed in the circumferential direction on the sliding surface of the rotating ring, and a groove is formed in the rotating ring from the sliding surface side to the back side facing the annular groove. A first pore-like communication hole that penetrates along the axial direction, and a first pore-like communication hole that does not penetrate along the axial direction from the sliding surface side to the back surface side adjacent to each other. and a second pore-like communication hole extending in the rotary ring, and a third communication hole facing from the outer periphery of the rotating ring is communicated with the second pore-like communication hole, and 3. A mechanical seal characterized in that the communication hole No. 3 is opened obliquely in a direction substantially tangential to the rotational direction of the rotating ring.
