ABSTRACT:
A fuel injection apparatus has a delivery pipe 7, an injector 8, fixing hooks 56 and fixing hook grooves 38. The delivery pipe 7 has an electric signal line and a connector 34, the connector 34 being placed at an end of the electric signal line. The injector 8 has an O-ring 52 and an injector side terminal 54 and is mounted to the delivery pipe 7, the O-ring 52 having a center P and sealing a gap between the delivery pipe 7 and the injector 8. The injector side terminal 54 is electrically connected with the connector 34. The fixing hooks 56 and the fixing hook grooves 38 prevent the injector side terminal 54 from sliding with respect to the connector 34 in the direction of an axis of the injector 8. The contacting points between the fixing hooks 56 and the fixing hook grooves 38 are positioned on a line L. The line L passes through the center P of the O-ring 52 and is perpendicular to the axis of the injector 8.
