<p>A sealing device (1) formed by combining a seal member (11) and a slinger (31), the seal member (11) having a first side lip (19) slidably in close contact with an axial end surface (33a) of the slinger (31), the seal member (11) further having a second side lip (20) disposed at a position that is on the outside of the first side lip (19) and is nearer an object to be sealed than the first side lip (19), wherein torque generated during the sliding is minimized as much as possible. To achieve this, the second side lip (20) is shaped so as to have smaller interference than the first side lip (19). The interference of the second side lip (20) may be set to zero by providing it with a labyrinth structure in which the second side lip (20) is not in contact with the axial end surface (33a) of the slinger (31).</p> |
