Abstract
A cylinder injecting fuel injection valve including a seal gasket sealing at least first two of three regions defined between the shoulder portion of the fuel injection valve main body, the shoulder portion of the cylinder head and an outer circumferential portion of the fuel injection valve main body. The gasket comprises an annular metallic elastic member and an annular support member elastically supporting the metallic elastic member. The gasket abuts at an abutting surface against the shoulder portion of the cylinder head at an axial position closer to the combustion chamber of the internal combustion engine than an upstream side end surface of the swirler member. The metallic elastic member of the gasket having a contacting surface contacting with an outer circumferential portion of the fuel injection valve main body, the end portion of the contacting surface of the metallic member being positioned at an axial position closer to the combustion chamber of the internal combustion engine than an upstream side end surface of the swirler member. The gasket having an inner circumferential surface opposing to an outer circumferential surface of at least the swirler body of the swirle…
