置。 For vehicles where negative pressure from a negative pressure pump is guided to a diaphragm actuator and the diaphragm actuator controls opening and closing of a throttle valve according to the difference between the actual vehicle speed and the vehicle speed set by a cruise command signal. In the automatic constant speed traveling system, a temperature-sensitive on-off valve is set in the negative pressure chamber of the diaphragm actuator, and the temperature-sensitive on-off valve is opened when the temperature is outside of a preset guaranteed temperature, thereby reducing the negative pressure of the diaphragm actuator. An automatic constant speed traveling device for a vehicle, characterized in that a pressure working chamber is configured to be open to the atmosphere.
