ABSTRACT:
A floating seal device includes a fixed side O-ring held by a fixed side seal retainer, a rotary side O-ring held by a rotary side seal retainer, and fixed side and rotary side seal rings pressed against each other by the respective O-rings so that their opposed surfaces may be slidably held in contact with each other. Such device is improved in order to eliminate oil leakage, to reduce mechanical power loss, to avoid an increase in weight and to shorten the replacement time for lubricant oil by mounting an oil absorbing member made of felt or the like to a peripheral wall surface formed on the opposed surface of the rotary side seal ring.
