A sealing device (1) capable of further increasing sealing performance by a labyrinth to effectively suppress the entry of dust such as slurry, comprising an inner peripheral side sealing member (2) fitted to an inner peripheral side mounting member as one of two members rotating relative to each other and an outer peripheral side sealing member (3) fitted to the outer peripheral side mounting member as the other. An outer peripheral tube part (4c) is formed on the outer peripheral portion of the metal ring (4) of the inner peripheral side sealing member (2), and a series of long labyrinth spaces (8), (9), and (10) are formed between the outer peripheral surface of the outer peripheral tube part (4c) and the outer peripheral side sealing member (3), between the tip face of the outer peripheral tube part (4c) and the outer peripheral side sealing member (3), and between the inner peripheral surface of the outer peripheral tube part (4c) and the outer peripheral side sealing member (3).
