Claims

[Scope of utility model registration request]

Equipped with a vehicle speed sensor that detects vehicle speed from the rotational speed of the driving wheels, an actuator that rotationally controls the throttle valve, and a control means that controls the actuator so that the vehicle speed reaches a target set speed based on the output signal of the vehicle speed sensor. Further, in a constant speed traveling device for a vehicle, which is equipped with an accelerator switch for increasing the vehicle speed at a predetermined acceleration rate during constant speed traveling control,
A constant speed traveling device for a vehicle, comprising an acceleration rate changing means for reducing the acceleration rate when acceleration control is performed after the acceleration rate exceeds a predetermined rate.
