関速度制御装置。a speed detection unit that detects an actual rotational speed of the internal combustion engine and outputs a speed detection signal; a speed setting signal that determines a set rotational speed of the internal combustion engine; and a maximum speed setting signal that determines a maximum allowable rotational speed of the internal combustion engine. a speed setting section that outputs the speed setting signal; a calculation section that receives the speed setting signal and the speed detection signal as input and outputs a control message necessary to make the actual rotation speed match the set rotation speed; and the maximum speed setting signal. an overspeed detection unit that receives the speed detection signal as input and outputs a deceleration command signal that instructs to decelerate the internal combustion engine when the rotational speed exceeds the maximum allowable rotational speed, and sets the actual rotational speed. A speed adjusting means for adjusting the speed of the internal combustion engine to match the rotational speed is operated in accordance with the control signal, and when the deceleration signal is input, the speed is adjusted so as to reduce the actual rotational speed of the internal combustion engine. In the internal combustion engine speed control device, the speed setting section includes a resistor series circuit formed by connecting a first and a second resistor in series, and a substantially constant current flowing through the resistor series circuit. a power supply circuit that allows a current to flow, at least the second resistor of the first and second resistors is configured to be able to adjust its resistance value, and the maximum speed setting signal is applied to both ends of the resistor series circuit. , and an internal combustion engine speed control device, wherein the speed setting signal is obtained at both ends of the second resistor.
