ものである。 The drive lever 11 and the rotation transmission lever 14 are connected to a single stay by the drive lever support hole 20 and rotation transmission lever support hole 21 provided in the stay plate 19, the appearance of which is shown in FIG. plate 19
As shown in FIG. 5, it is attached to the carburetor main body through a drive lever support hole 20 with a screw 22. Note that 23 is a throttle wire cable holding hole. A return spring 24 is coaxially attached to the drive lever 11, and one end of the return spring 24 is engaged with a stop screw attachment rib provided on the carburetor body.
The other end of the return spring is locked to the rotation regulating stopper 25 of the drive lever 11, and both ends of the return spring are connected to the seventh
As shown in the figure, a spring holding portion 26 provided on a part of the drive lever and a spring holding portion 28 provided on a mounting collar 27.
Since the drive lever 11 is held by
There is no spring jamming into the rotating part during rotation operation.
