<p>The remote controller outputs an electrical operation signal from an operation device (10) to the driving device (6) of a governor mechanism (2) of an engine (1) to remote-control the governor mechanism. This remote controller includes a detection device (8) for detecting a control quantity of the governor mechanism and a control device (13) to which an operation signal from the operation device (10) and a detection signal from the detection device (8) are input. When the difference between a control quantity at a certain time and a control quantity detected a predetermined prior to that time is below a predetermined value, this control device (13) judges this state as an operation limit of the governor mechanism (2). It outputs a stop signal to the driving device (6).</p>
