The known floating seal device including 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, is improved in order to eliminate oil leakage to, reduce mechanical power loss, to avoid increase of a weight and to shorten a replacement time for lubricant oil. The improvement resides in that an oil absorbing member made of felt or the like is mounted to a peripheral wall surface formed on the opposed surface of the rotary side seal ring.
