置。 A bypass air passage branched from the starter air passage of the carburetor is connected to the downstream side of the throttle valve of the intake pipe, and this bypass air passage is operated by a diaphragm valve that operates when the negative pressure in the intake pipe exceeds a set value. An intake pipe of a carburetor, characterized in that it is formed to be openable and closable, and when the negative pressure inside the intake pipe exceeds a certain value, air is replenished into the intake pipe to maintain the negative pressure inside the intake pipe within a set value. Negative pressure control device.
