とするメカニカルシール。 It has a rotating side sealing element equipped with a rotating sealing ring that rotates simultaneously with the rotating shaft of the sealed equipment, and a stationary side sealing element equipped with a stationary sealing ring fixed to the casing side of the sealed equipment. In a mechanical seal in which the sealing end surfaces of a ring and a stationary sealing ring are brought into sliding contact to form a shaft sealing part, the rotating side seal element externally fits a central boss part onto the rotating shaft and a peripheral part is attached to the rotating sealing ring. The fitted annular packing, the annular part that reduces the diameter of the central boss part and fixes it to the rotating shaft, and the annular part that extends radially outward from the annular part and engages with the rotating sealing ring to apply rotational force. A mechanical seal comprising a leaf spring member formed with a plurality of pressing pieces for transmitting power and urging the stationary seal ring toward the stationary seal ring.
