{Technical Problem} An object is to provide a sliding component that can seal and lubricate at the same time by reducing the amount of leakage of sealed fluid further while preventing torque increase and local wear. {Solution to Problem} The sliding component is characterized in that an extremely shallow step of circular shape is provided on the sealing face of one of a pair of sliding parts that slide against each other in such a way that the step is positioned on the low-pressure fluid side (atmosphere side) of this sealing face and also set lower than the sealing face, and that pumping grooves acting to push back toward the high-pressure fluid side (sealed fluid side) the fluid that tends to leak from the sealing face toward the low-pressure fluid side (atmosphere side) are provided on the surface of the extremely shallow step. |
