PROBLEM TO BE SOLVED: To provide a floating seal with a high quality and a low price.SOLUTION: In the floating seal 1, a gap between a fixed floating seat 2 and a stationary housing 12 is sealed by a fixed seal ring 18 and a gap between a rotation floating seat 7 and a rotation housing 15 is sealed by a rotation seal ring 19. Slide surfaces 5, 10 of both floating seats 2, 7 are press-contacted with each other by a cooperation of both seal rings 18, 19 to seal a gap between both slide surfaces 5, 10. The fixed floating seat 2 and the rotation floating seat 7 are manufactured by a powder metallurgy method. Problems such as a defect, e.g. shrinkage cavity, a weight fluctuation, a maladjustment of dimension and the like are not generated at both floating seats 2, 7. Thereby, the floating seal with a high quality can be provided. Since cutting chips discharged from a machine factory, etc., can be used for a raw material, a manufacture cost can be outstandingly reduced.COPYRIGHT: (C)2002,JPO
