Abstract
The invention relates to a combustion gas seal for injectors and to a seal structure disposed therewith, for preventing leakage of combustion gas in a state in which an injector is mounted to an engine head. And, the number of parts is reduced, vibration and noise are reduced, and sealing performance is improved. A tapered surface, in which an clearance between the tapered surface and an inner peripheral surface of a mounting hole of the engine head narrows from an engine bore side towards an atmospheric side, is disposed at a groove bottom of an attachment groove of the injector, and an abutment portion that abuts against the tapered surface is disposed at the combustion gas seal for injectors.
