。A leak hole connecting first and second negative pressure chambers separated by a diaphragm, a negative pressure signal passage communicating the second negative pressure chamber with an intake manifold downstream of the throttle valve, and an intake air downstream of the throttle valve. By providing an air passage that communicates the manifold with the atmosphere, a valve connected to the diaphragm I to open and close the air passage, and means for always biasing the valve in the closing direction, In an internal combustion engine speed reduction device comprising a normally closed anti-afterburn valve configured to open the valve based on the pressure difference between the two page pressure chambers when negative pressure suddenly increases, A one-way valve that opens when the negative pressure is equal to or higher than a predetermined pressure is provided, and the first negative pressure chamber of the anti-afterburn valve is communicated with the intake manifold downstream of the throttle valve through the one-way valve. Characteristic reduction gear for internal combustion engines.
