Abstract
A sealing structure in which sealing is made by a seal ring installed in a dovetail groove where only an inner surface on one side of the groove is an inclined surface. In the sealing structure, the seal ring is less likely to come out of the dovetail groove, resistance of insertion of the seal ring into the dovetail is small, and particles are less likely to occur in the structure. The seal ring is formed of a rubber-like elastic material and is installed in the dovetail groove where the first inner surface on one side of the groove is inclined falling to the inside of the groove.
