A dust entry reduction meansfor 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. 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.
