Abstract
In an embodiment, a sliding face of at least one sliding part of the pair of sliding parts is provided, along its entire circumference, with a trap groove 10 for trapping leakage fluid, located on a leakage side and spaced from the leakage side by a land. A dust entry reduction means 12 for reducing entry of dust from the leakage side while allowing passage of fluid is formed between lands of the pair of sliding parts on the leakage side of the trap groove 10. At the sliding faces of the pair of sliding parts sliding relatively, entry of dust from the leakage side as well as liquid leakage to the leakage side are suppressed.
