<p>Provided is a sealing structure which has increased sealing performance and which can be mounted with a reduced mounting load. An annular groove (211) has a stepped section provided on the bottom thereof and is provided with: a primary annular groove (211a) located on one side of the groove relative to the stepped section; and a secondary annular groove (211b) located on the other side of the groove relative to the stepped section. The sealing device is characterized in that a gasket (400) is disposed so as to be fitted in the primary annular groove (211a) and in that the gap (D2) between an injector and a mounting hole measured at the boundary between the primary annular groove (211a) and the secondary annular groove (211b) is greater than a minute gap (D1) on the opposite side of the primary annular groove (211a) from the secondary annular groove (211b).</p> |
