ニカルシール。[Claims for Utility Model Registration] 1. A stationary side sliding ring that is airtightly supported on the housing side and a rotating side sliding ring that is airtightly supported on the shaft side, and that the rotating side sliding ring is airtightly supported on the shaft side. In a dry sliding type mechanical seal having an annular groove concentric with the annular sliding surface of a moving ring, the annular groove is partially opened to the outside of the sliding surface of the stationary sliding ring. A dry sliding type mechanical seal characterized in that the outer edge of the sliding surface of the stationary side sliding ring is formed into a non-circular shape. 2. A claim characterized in that a protrusion projecting into the annular groove is provided on the outer edge of the sliding surface of the stationary sliding ring at a position into which the annular groove enters as the rotating sliding ring rotates. 1. The dry sliding mechanical seal described in 1.
