器のフアストアイドル装置。 A fast idle device for a carburetor that opens and closes a throttle valve via an operating lever mounted around a throttle shaft by a cam surface of an interlocking cam that is interlocked by a temperature-responsive member. respectively form a starting cam surface and a warm-up cam surface that selectively engage with the engaging pin of the operating lever, and a predetermined position of the carburetor body is provided with the engaging pin of the operating lever when starting the engine. A diaphragm device is provided with a diaphragm device that holds the operating lever at a position where it contacts the starting cam surface and that moves backward when the engine negative pressure reaches a predetermined value or more, and that the actuating rod moves backward. Further, when the actuating lever is rotated in the valve closing direction by the biasing force of the return spring of the throttle valve, the engagement pin of the lever is configured to come into contact with the warm-up cam surface. A fast idle device for a carburetor, characterized by:
