Sliding parts comprising an annular stationary ring fixed on a fixed side and an annular rotating ring that rotates along with a rotating shaft oppose each other and sealing faces are caused to rotate relative to one another, whereby a sealed fluid present on one side in the radial direction of the relatively rotating sealing faces is sealed; the sliding parts characterized in that: a plurality of circumferentially separated sealed-fluid-accommodating blocks are formed on either of the sealing faces of said stationary ring or rotating ring so as to communicate with a sealed fluid-containing space; said plurality of sealed-fluid-accommodating blocks has an indented shape at a different level than the sealing face so as to be able to accommodate the sealed fluid; 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 said plurality of sealed-fluid-accommodating blocks; a plurality of parallel linear indentations having the depth between the apexes and the troughs thereof is formed in each of the pumping areas, an imaginary plane connecting the apexes of the indentations is set lower than the sealing face, and the imaginary plane forms a level difference with respect to the sealing face; the pumping areas formed on the bottom of said 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 said 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. a plurality of circumferentially separated sealed-fluid-accommodating blocks are formed on either of the sealing faces of said stationary ring or rotating ring so as to communicate with a sealed fluid-containing space; said plurality of sealed-fluid-accommodating blocks has an indented shape at a different level than the sealing face so as to be able to accommodate the sealed fluid; 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 said plurality of sealed-fluid-accommodating blocks; a plurality of parallel linear indentations having the depth between the apexes and the troughs thereof is formed in each of the pumping areas, an imaginary plane connecting the apexes of the indentations is set lower than the sealing face, and the imaginary plane forms a level difference with respect to the sealing face; the pumping areas formed on the bottom of said 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 said 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.
