摘要：
To improve sealing performance by a labyrinth to inhibit entry of dust, a sealing device (1) comprising an inner peripheral side sealing member (2) fitted to an inner peripheral side mounting member and an outer peripheral side sealing member (3) fitted to the outer peripheral side mounting member, both relatively rotating, has an outer peripheral tube part (4c) 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, 10) is formed between the outer peripheral surface of the outer peripheral tube part (4c) and the outer peripheral side sealing member (3), between the end 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).
