A variable venturi type carburetor is described which consists of a carburetor body provided with a suction passage therein, a slide valve supported by the body for movement across the suction passage to function as a variable venturi, a butterfly throttle valve pivotably supported by the carburetor body downstream of the slide valve, an interlocking means connecting the slide valve and the butterfly throttle valve for operation in correspondence with one another. The carburetor body comprises a side portion including a wall defining a housing recess, and a cover member fixed to the carburetor body to close the housing recess and form a housing chamber in which the interlocking means is arranged. The cover member includes an integral loosening-preventing portion, the interlocking means including a setting nut associated with the slide valve. The loosening-preventing portion engages the setting nut for preventing turning thereof, thereby to prevent the setting nut from being loosened.
