To effectively reduce operational noise generated by vibration of the fuel injection valve with a fuel injection valve installation structure of an engine. In the structure, an installation hole is formed in an engine component member that constitutes a part of an engine. The installation hole has an annular shoulder portion, which is formed in the middle portion thereof, and which faces the exterior side. The fuel injection valve is held between the annular shoulder portion and a supporting member attached to the engine component member. A first damper, with high vibration-damping properties, is set between an annular shoulder portion and a fuel injection valve. A second damper, with high vibration-damping quality, is set between a supporting member and the fuel injection valve.
