[Object] To provide a sliding component in which there is no leakage when no motion is occurring, action takes place with fluid lubrication and leakage is prevented during rotation including the start of rotation, and both sealing and lubrication can be achieved. [Means of Achievement] A positive pressure generating mechanism comprising a positive pressure generating groove is provided to a high-pressure side of one of two sliding surfaces that slide relative to each other in a pair of sliding components, and a negative pressure generating mechanism comprising a negative pressure generating groove is provided to a low-pressure side, said positive pressure generating groove and negative pressure generating groove being communicated with a high-pressure fluid side and separated from a low-pressure fluid side by a seal surface. |
