PROBLEM TO BE SOLVED: To provide a sealing device capable of suppressing buckling breakage while suppressing an increasing sliding resistance between a seal ring and a housing.SOLUTION: A sealing device includes a resin-made seal ring 10 arranged to be slidable with respect to a cylinder inside surface and a rubber-like resilient buckling arranged to be in close contact with an inside surface of the seal ring 10 and a bottom surface of an annular groove. In addition, the seal ring 10 has in one location in a circumferential direction, an abutment 11 cut stepwise when viewed both from the outside surface and the inside surface, and in the abutment 11, an end face and an inside surface, which confront with each other, are tied together by a curved surface 12. |
