<p>A governor device (11) enabling the easy setting of a fuel injection amount limitation start position for a reduced rotational speed from the outside, comprising a first lever (31) interlockingly connecting a governor lever (30) to a rotational speed set lever (29), a second lever (32) pivotally supported on the first lever (31), and a third lever (33) pivotally supported on the second lever (32) to restrict a rotation amount by the second lever (32) and interlocked with a governor weight (22). An elastic member (38) energizing the first lever (31) and the second lever (32) to reduce the rotational speed by a specified amount at a low rotational speed is installed between the first lever (31) and the second lever (32), and a set load changing means (50) for the elastic member (38) is fitted to the first lever (31) near the elastic member (38).</p>
