。 A stationary sealing ring that can slide into sliding contact with the rotating sealing ring on the rotating shaft side is engaged with a double-tube structure holder that is fixedly held on the seal casing, and a ring that expands and contracts in the axial direction is inserted between the holder and the stationary sealing ring. In a mechanical seal equipped with a bellows, the stationary seal ring is held by engaging the engagement groove formed on the outer periphery of the stationary seal ring with the engagement protrusion formed on the outer cylindrical part of the holder. The bellows is held in a non-rotatable and axially movable manner by the body, and the inner cylindrical part of the holding body is formed into a short shape that fits and holds only the end of the bellows and does not come into contact with the expandable part of the bellows. mechanical seal.
