動チヨーク装置。 A cam lever integrally having a cam for determining the first idle opening degree of the throttle valve is rotatably supported on the carburetor body, and is brought into contact with the drive shaft of the temperature-sensitive actuation means that responds to changes in ambient temperature. The cam lever is biased by a spring, and a torsion spring is interposed between a driven gear meshing with a sector gear interlocking with the cam lever and a chiyoke valve shaft having a chiyoke valve and rotatably supported on the carburetor body. In an automatic check valve device for a carburetor, a support shaft fixed to the carburetor body has a cam lever and a support shaft that can come into contact with the cam lever from the rear side along the direction of rotation of the check valve opening around the support shaft. A gear lever integrally having a sector gear is supported for relative rotation, and a first spring is interposed between the cam lever and the carburetor body to exert a spring force in a direction to bring the cam lever into contact with the temperature-sensitive actuation means. A second spring is interposed between the cam lever and the gear lever and generates a spring force in a direction that brings them into contact with each other, and a driven gear is fitted into the chiyoke valve shaft so as to be rotatable with respect to the other. A contact plate that can come into contact with the driven gear from the front side along the rotation direction of the valve opening around the valve shaft is fixedly installed, and a spring force is applied between the driven gear and the contact plate in the direction of bringing them into contact. An automatic control device for a carburetor, characterized in that it is equipped with a torsion spring that exhibits
