Claims

[Claims for Utility Model Registration] (1) In a constant speed driving device that compares a vehicle speed signal and a set vehicle speed and operates a throttle valve according to the difference to make the traveling vehicle speed match the set vehicle speed, A constant speed traveling device characterized by being provided with means for canceling constant speed traveling when the amount of change exceeds a reference amount of change. (2) A utility model characterized in that the utility model further comprises a storage unit that stores the immediately preceding change width of the vehicle speed signal when constant speed driving is canceled due to the amount of change of the vehicle speed signal being equal to or greater than the reference amount of change. A constant speed traveling device according to claim 1.
