The present invention provides a gasket and a sealing structure capable of exhibiting stable sealing performance even when used in a high-temperature environment.
A gasket 100 is mounted in an annular mounting groove 210 provided to a first member 200 and makes tight contact with a groove bottom surface 211 of this mounting groove 210 and an end face 310 of a second member 300, to seal a gap between the first member 200 and the second member 300. A perimeter of an outer circumferential surface 130 of the gasket 100 is designed to be not greater than a perimeter of a radially outer side wall surface 212 of the mounting groove 210 in a condition with a highest temperature in an environment of use. |
