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 (S) 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 (S) 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 (S) 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 (S) 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 (d2) 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 (S), and the imaginary plane forms a level difference (d1) with respect to the sealing face (S); 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 (S) on which said sealed-fluid-accommodating blocks are formed, the seal dam area being on the opposite side of the sealing face (S) relative to the sealed-fluid side. a plurality of circumferentially separated sealed-fluid-accommodating blocks are formed on either of the sealing faces (S) 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 (S) 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 (d2) 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 (S), and the imaginary plane forms a level difference (d1) with respect to the sealing face (S); 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 (S) on which said sealed-fluid-accommodating blocks are formed, the seal dam area being on the opposite side of the sealing face (S) relative to the sealed-fluid side. <EOS>
