Claims

[Claims for Utility Model Registration] (1) An opening/closing mechanism that opens and closes the throttle valve of an engine mounted on a vehicle and a drive motor that drives the opening/closing mechanism, and which opens and closes the throttle valve during constant speed driving control. The clutch means, which transmits the driving force of the drive motor to the opening/closing mechanism by engaging the mechanism and the drive motor, is activated by a cancel signal output from a constant speed running release switch including a brake pedal switch that detects depression of the brake pedal. In a constant-speed traveling device that disengages, when the cancel signal is output from a constant-speed traveling release switch other than the brake pedal switch, the throttle valve controls the drive motor before disengaging the clutch means. A constant speed traveling device characterized by operating in the direction of closing a valve. (2) The clutch means is disengaged when the throttle valve is closed to a predetermined opening degree by operating the drive motor in a direction in which the throttle valve is closed. The constant speed traveling device described. (3) when a predetermined period of time has elapsed since the drive motor was operated in a direction in which the throttle valve was closed;
2. A constant speed traveling device according to claim 1, wherein said clutch means is disengaged. (4) The constant speed traveling device according to any one of claims 1 to 3, wherein the drive motor is operated at a higher speed than during the constant speed traveling control when the cancel signal is output.
