Abstract
A sealing device is constructed by combination of a lip seal member attached to a not-rotating stationary member and a seal flange member attached to a rotary member. The seal lip member has a lip seal member main body having an end face lip, an outward flange portion, and an outer peripheral tube portion. The seal flange member has a seal flange member main body and an outer peripheral side tubular portion. The sealing device further includes a non-contact type labyrinth seal having a predetermined axial length arranged between the outer peripheral tube portion in the lip seal member and the outer peripheral side tubular portion in the seal flange member. The sealing device can improve sealing performance, particularly muddy water sealing performance, while fulfilling the need for low torque.
