{Technical Problem} To provide sliding parts that do not leak when stopped, operate under fluid lubrication and prevent leakage when rotating, including during initial rotations, and are capable of striking a balance between airtightness and lubrication. {Solution to Problem} A plurality of circumferentially separated sealed-fluid-accommodating blocks are formed on either of the sealing faces of a stationary ring or rotating ring so as to communicate with a sealed fluid-containing space; pumping areas for generating a pumping action due to the sliding of the stationary ring and the rotating ring in relative rotation are formed on the bottom of the plurality of sealed-fluid-accommodating blocks; the pumping areas formed on the bottom of the plurality of sealed-fluid-accommodating blocks are provided with intake pumping areas operating in a direction so as to draw in the sealed fluid and outflow pumping areas operating in a direction so as to expel the sealed fluid; and a plurality of dimples are disposed on a seal dam area on a side of the sealing face on which the sealed-fluid-accommodating blocks are formed, the seal dam area being on the opposite side of the sealing face relative to the sealed-fluid side. |
