[Scope of Claim for Utility Model Registration] (1) A control sleeve is slidably fitted to the plunger of a fuel injection pump, and a control rod arranged perpendicular to the plunger is engaged with the control sleeve, In the pre-stroke control device for a fuel injection pump, the control rod is rotated about its axis to change the axial position of the control sleeve relative to the plunger, thereby adjusting the pre-stroke. A direct-acting differential transformer is provided as a sensor for measuring the rotational displacement of the rod, and the movable core of this operating transformer is connected to the control rod via a mechanism that converts linear motion into oscillating motion. A pre-stroke control device for a fuel injection pump, characterized in that a movable iron core is used as a counterweight balanced with a control sleeve. (2) A control sleeve is slidably fitted onto the plunger of the fuel injection pump, a control rod arranged perpendicular to the plunger is engaged with the control sleeve, and the control rod is rotated along its axis. A pre-stroke control device for a fuel injection pump that changes the axial position of the control sleeve with respect to the plunger by rotating it around its center, thereby adjusting the pre-stroke. An electromagnetic actuator is provided, and the movable core of the electromagnetic actuator is connected to the control rod via a mechanism that converts linear motion into oscillating motion, and the movable core is used as a counterweight balanced with the control sleeve. A pre-stroke control device for a fuel injection pump, characterized in that:
