ことを特徴とするエンジンのアイドルアップ装置。A diaphragm mechanism that shifts the closing position of the throttle valve of the carburetor from the normal position to the opening direction by a predetermined amount only when atmospheric pressure is introduced into the negative pressure introduction chamber, and this diaphragm mechanism moves the idle up to the negative pressure introduction chamber. A pressure introduction line for introducing atmospheric pressure or negative pressure for canceling idle up, a switching valve for switching this pressure introduction line to an atmospheric pressure introduction state or a negative pressure introduction state, and a diaphragm actuated by boost pressure. and an operating mechanism that switches the switching valve using the operating force of the diaphragm, and when the boost pressure shifts to the atmospheric pressure side by a predetermined value from the boost pressure during normal idling operation, the switching valve An engine idle-up device characterized in that the engine is set to switch from a negative pressure introduction state to an atmospheric pressure introduction state.
