Abstract

PURPOSE: To prevent a drive shaft mechanism from vibrating by providing projections 9a onto the front end surface of a fuel injection pump drive gear in a timing gear casing and by providing a magnetic detector in opposite to the projections for detecting a speed of a fuel injection pump so that the distance between the fuel injection pump and the gear casing is shortened.
CONSTITUTION: A fuel injection pump drive unit comprises a timing gear casing 8, a fuel injection pump drive gear 9 secured to the front end of a fuel injection pump drive shaft 5 and an idle gear 10. A plurality of projections in the number which is integer times as many as the number of the engine cylinders, are provided on the front end surface of the drive gear 9, and a boss 8A is provided on the front end wall of the gear casing 8 in opposite to the projections 9a, for mounting a non-contact detector 11 such as, for example, a magnetic sensor for detecting the speed of the drive shaft 5. Accordingly, since a conventional speed detector 6 may be eliminated, the distance L between the front end surface of a fuel injection pump 2 and the rear end surface of the timing gear casing 8 becomes short, thereby vibration in the shaft mechanism such as, for example, the drive shaft 5 is prevented from occurring.
