One end is fixed to a diaphragm that defines a negative pressure chamber, and the other end is used to control the throttle of an internal combustion engine to increase the throttle valve idle opening in response to an increase in negative pressure within the negative pressure chamber. A negative pressure actuator with an output Rondo linked to a valve, a load determination circuit that determines the operation of an on-vehicle electrical device and outputs a signal when the on-vehicle electrical device is activated, and a negative pressure actuator that outputs a negative pressure signal from a negative pressure source to a negative pressure control valve that controls negative pressure introduced into the pressure chamber; and a negative pressure control valve that is driven in accordance with an output signal of the negative pressure discrimination circuit to generate a negative pressure in the negative pressure chamber according to the output signal. [An in-vehicle electric device that increases the idle speed of the engine by increasing the idle opening of the throttle valve according to the load of the on-vehicle device. In the load-responsive negative pressure fast idle device, ``the load discrimination circuit has a first output port that outputs a signal when any one of the multiple vehicle-mounted electrical devices is activated; a second output port for outputting a signal, and the drive circuit controls the negative pressure control valve to a predetermined first output port when the signal is output from only the first output port.
The negative pressure control valve is opened to a valve opening degree, but when a signal is output from a second output port, the negative pressure control valve is opened to a second valve opening degree, which is larger than the first valve opening degree. An on-vehicle electrical system for an engine is a negative pressure fast idle device that responds to load. 2. The load discrimination circuit includes a first OR circuit including the first output port, a first OR circuit including the second output port, and a plurality of ANDs.
