Conventionally, in such an operating amount adjusting device, for example, an idle opening adjustment device for a throttle valve, a threaded member for adjusting the idle opening is screwed onto the carburetor main body so that its protrusion amount can be freely adjusted, and the throttle valve lever is screwed into the carburetor body. By bringing it into contact with the member,
The limit angular displacement of the throttle valve lever is adjusted to correspond to the idle opening of the throttle valve. However, in such a conventional device, a screw hole or the like must be formed in connection with the screw member, which complicates the structure and requires a spring member to prevent the screw member from loosening. In addition, when the carburetor is made of resin in order to reduce its weight, the threaded parts of the conventional structure due to the IJ-pump phenomenon peculiar to synthetic resins. Because the supporting bracket part deforms and the screws become loose,
It is also one of the factors that prevents weight reduction of vaporizers by using resin.
