Claims (1)

[Scope of Claim for Utility Model Registration] In a safety device for a constant-speed traveling device that controls the opening and closing of an engine throttle valve via an actuator to maintain a set vehicle speed and travel at a constant speed, a canceling means for determining whether to cancel the constant speed traveling control when the throttle valve has decreased, and when the canceling means determines to cancel the constant speed traveling control and closes the throttle valve, the closing stroke of the throttle valve closes the throttle valve; 1. A safety device for a constant speed traveling device characterized by having: a slow deceleration means having a stroke that gently performs the above steps;
