る内燃機関のアイドルアップ装置。゛ Negative pressure introduced into the diaphragm chamber provided in an internal combustion engine that controls the idle speed of the engine by controlling the flow rate of the amount of intake air introduced through the bias that bypasses the throttle valve. An idle rotation speed control valve that opens the bypass when , and a control device for opening the negative pressure switching valve, wherein the device is arranged in an output circuit of the control device, and the negative pressure is kept constant according to the intake manifold negative pressure. A negative pressure switch that turns off when the negative pressure exceeds a value, and a negative pressure delay valve that is arranged in the negative pressure line and transmits the negative pressure with a delay, are provided to guide the intake manifold negative pressure to the negative pressure switch. An idle up device for an internal combustion engine featuring:
