PROBLEM TO BE SOLVED: To improve the annular seat holding property, and to show the stabilized sealing function in a sealing device having the annular resin seat. SOLUTION: In a sealing device 1 formed by holding an annular resin seat 10 with two metal rings 20, 30, the inner surface of a part of any one of the metal rings 20 (30) for pinching the annular seat 10 is provided with a recessed part 33 (24) so that a part of the annular seat 10 inserted by the compression pinching force is hooked thereon in the rotating direction. Rotation of the annular seat 10 with a rotary member 3 is prevented by hooking the annular seat 10 on the recessed part 33 (24). |
