摘要： A fuel injection apparatus of an internal combustion engine includes a fuel injection pump for injecting a fuel in a quantity corresponding to the position of a control rack; a start spring, a control spring and an idling sub-spring, for biasing the control rack in a fuel injection quantity increasing direction; an adjusting lever for adjusting a spring load of the control spring; a governor including a fly weight rotating with the fuel injection pump and moving the control rack in a fuel injection quantity decreasing direction by the centrifugal force; and a stopper mechanism for limiting the movement of the control rack in the fuel injection quantity increasing direction; wherein the stopper mechanism comprises a stopper opposing an end portion of the control rack and an elastic member for biasing and holding the stopper toward and at a stop position, and the elastic force of the elastic member is greater than the sum of the spring load of the start spring and the spring load of the idling sub-spring when the adjusting lever is at an idling position, and is smaller than the sum of the spring load of the start spring, the spring load of the control spring and the spring load of the idling sub-spring when the adjusting lever is at a partial position.
