One of the pair of sliding rings is attached to the inner periphery of the housing and the other to the outer periphery of the shaft in an airtight manner, and both rings are slid closely against each other by the axial load from the spring. In a dry sliding mechanical seal having an annular groove concentric with the sliding surface of the sliding ring, the hard sliding ring has one end opening toward the annular groove and the other end opening at the opening location. A through hole is bored at a location lower than the annular groove, and the inside of the annular groove is opened to the outside through the through hole, and the annular groove of the through hole is formed on the end surface of the hard side sliding ring. At a position near the side opening and on the rotational direction side when viewed from the opening,
A dry sliding type mechanical seal characterized in that a protrusion projecting into the annular groove is provided.
