関の減速装置。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 to open and close the air passage, and means for always biasing the valve in the closing direction, the negative impact downstream of the throttle valve is reduced. In an internal combustion engine speed reduction device comprising a normally closed anti-afterburn valve configured to open a front valve by the pressure difference between the two negative pressure chambers when the pressure suddenly increases, when the pressure difference is equal to or higher than a predetermined value. A one-way valve is provided whose pressure receiving portion is a spherical plate spring that opens when reversed, and the first negative pressure chamber of the anti-afterburn valve is connected to the second negative pressure chamber through the one-way valve. A deceleration device for an internal combustion engine, characterized in that the anti-afterburn valve is configured to communicate with a pressure chamber so as to stop the operation of the anti-afterburn valve when the one-way valve opens due to a rise in differential pressure.
