摘要： A mechanical seal that prevents deposition of a degradation material generated on a sliding interface is to be provided. In a mechanical seal including a sleeve that rotates with a rotating shaft, a seal cover fixed to a housing, a rotating ring attached to the sleeve and a fixed ring attached to the seal cover and disposed in sliding-contact with the rotating ring via a sliding interface perpendicular to the rotating shaft, a scraping member is provided on the sleeve at a position close to an inner edge of the sliding interface so as to remove a degradation material from the inner edge of the sliding interface. Alternatively a discharging structure is formed on the sleeve so as to discharge the fluid stuck to the sleeve 4 to outside of the seal cover by the rotation of the sleeve. Otherwise, a solvent or an inert gas may be filled in a space defined by the sleeve 4, the rotating ring 6, the fixed ring 7 and the seal cover 5.
