ABSTRACT:
In a rotational speed control apparatus for an internal combustion engine in which a signal-responsive diaphragm, whose controlling position is determined by a controlled negative pressure signal, is provided with a valve member controlling to negative pressure acting upon a driving diaphragm controlling the opening of a throttle valve, the negative pressure acting upon the driving diaphragm, when the controlled negative pressure signal is detected to be not normal, is controlled to be shifted to the level at which the driving diaphragm is rendered substantially non-operable.
