Abstract
A fuel injection valve is mounted in a cylinder head by being inserted in an insertion hole provided in the cylinder head. A shoulder section is provided at the inlet portion of the insertion hole to be expanded in an annular shape. The fuel injection valve is provided with a stepped section expanded in diameter in a tapered manner to have a tapered surface facing the shoulder section. A vibration insulator is disposed between the stepped section and the shoulder section. The vibration insulator is provided with a circular annular tolerance ring making contact with the tapered surface of the fuel injection valve. A circular annular sleeve section coaxial with the tolerance ring is integrally formed on the tolerance ring to extend from the surface of a portion of the tolerance ring, the portion not facing the tapered surface of the fuel injection valve.
