。[Scope of claim for utility model registration] 1. A control circuit that compares the vehicle speed set by a control switch with the actual vehicle speed and outputs a control signal so that the actual vehicle speed approaches the set vehicle speed, and a throttle provided in the intake passage of the engine. an actuator that adjusts the valve to a set opening according to an input signal; an actuator output circuit that converts a control signal from the control circuit into a drive signal for driving the actuator; and an actuator output circuit that detects an abnormality in the drive signal to the actuator. A constant speed traveling device comprising: an abnormality detection circuit that outputs an abnormality signal when an abnormality signal is detected; and a power cutoff circuit that cuts off power to at least the actuator output circuit when the abnormality detection circuit receives an output. 2. The constant speed traveling device according to claim 1, wherein the power cutoff circuit also cuts off the power to the control circuit when the abnormality detection circuit receives an output.
