れたことを特徴とする内燃機関の点火時期制御装置。[Scope of Claim for Utility Model Registration] Negative pressure control having a Meillet diaphragm i and a sub-diaphragm chamber connected via a negative pressure pipe to an advance port formed upstream of the opening of the throttle valve IJ in the intake passage. the main diaphragm of the device and the advance port and negative pressure control device. A negative pressure switching valve that is disposed in the middle of a negative pressure pipe connecting the ram chamber and that is turned ON when cold or during a specific shift, and an EGR port that is formed further upstream of the advance port and the advance port. and a negative pressure control valve that cuts off the transmission of the atmosphere to the main diaphragm chamber only when the generated negative pressure differential exceeds a predetermined value, and when the negative pressure switching valve is ON, and Negative pressure switching valve is OFF
When the differential pressure between the negative pressure generated between the advance port and the EGR port exceeds a predetermined value, the negative pressure generated at the advance port is introduced into the main diaphragm chamber and sub-diaphragm chamber of the negative pressure control device. An ignition timing control device for an internal combustion engine, characterized in that it is configured to:
