The grommet 5, which has a horizontal U-shaped cross section, and the spring plates 7a and 7b, which have a horizontal U-shaped cross section and which are superimposed inside the grommet 5, are deformed so as to maintain a high elastic restoring force. That is, each spring plate 7a, 7
The bent portions 8a and 8b of b are deformed into an annular shape and are in a state where they are no longer crushed. Therefore, the structure can withstand repeated stress caused by combustion cycles over a long period of time, and the sealing effect can be maintained over a long period of time.
