させた エンジンの空燃比制御装置。[Claims for Utility Model Registration] When a first pressure introduction passage and a second pressure introduction passage communicate with a diaphragm pressure chamber defined by a diaphragm connected to a throttle valve of a carburetor, and the diaphragm makes a predetermined stroke. , comprising a valve device that closes the first pressure introduction passage, the first pressure introduction passage is connected to a negative pressure passage downstream of the throttle valve that introduces intake negative pressure, and the second pressure introduction passage introduces atmospheric air. The throttle valve is operated by a two-stage actuating diaphragm device that maintains the predetermined stroke when the throttle valve communicates with the atmospheric passage, and maintains the full stroke when both pressure introduction passages are connected to the negative pressure passage that introduces negative pressure in the intake pipe downstream of the throttle valve. An air-fuel ratio control device for an engine that controls a valve opening degree, the air-fuel ratio control device for an engine having the atmospheric passage communicated with an air bleed passage of a carburetor.
