To reduce a difference in governors by a simple mechanical constitution in a centrifugal governor device.

One end of a governor lever 2 is pivotally supported to be slidable to a base end shaft 3, and tensile force of a governor force 6 and a governor spring 7 acts on the governor lever 2. The governor spring 7 is coupled to a governor lever 8 in an interlocking manner. An actuator 17 is engaged to the tip of the governor lever 8. When control rack 5 is determined to be in a position equal to or lower than a predetermined load position, operating section 18 of the actuator 17 pushes the tip of the governor lever 8 to turmingly move the governor lever 8 to a position so as to abut on a low engine speed setting limit volt 13.
