ルシール。 a pair of rotary-side seal elements disposed to be displaced in the axial direction of the rotary shaft, each having a rotary sealing ring;
A pair of stationary side seal elements are fixed to the housing side of the shaft-sealed equipment and each has a stationary seal ring, and the seal ring rotates by the spring force of a coil spelling interposed between the rotating side seal elements. In a one-coil double mechanical seal, the sealing end surfaces of the two are urged toward the stationary sealing ring side to form a shaft sealing part and sealing. A torque transmission ring is fixed so as to be rotatable at the same time, and the torque transmission ring and each rotary side seal element are connected to each other so as to transmit torque by an engagement mechanism that is formed on both and engage with each other. One coil double mechanical seal.
