In the above conventional example, FIG.
As shown in FIG.
Is loosely fitted to eliminate the interference between the two coil springs 7, 8. However, when the speed control lever 5 is swung from the idle operation state to the rated operation state, the two coil springs 7, 8 are rotated.
The lower end hooks 7b and 8b move along the arc of the circular hook engagement hole 18, and the engagement / contact state is not always constant, so that the engine speed varies.

It is conceivable to form the hook engaging hole 18 of the speed control lever 5 in the same hole as the hook engaging long hole 17 formed in the second lever 3B. When the rocking operation is performed, the lower end hook 7b of the service coil spring 7 minutely moves along the upper arc of the long hole, causing a slight variation in the engine speed. The engagement and contact of the upper hooks 7a and 8a of both coil springs 7 and 8 in the hook engagement slot 17 of the governor lever 3 is stable. This is because the swing range of the governor lever 3 is small.

In this embodiment, the hook engaging hole 18 of the governing lever 5 is formed so as to be narrowed upward in the direction of the axis x of the governor sprink 6, and the lower end hooks 7 b and 8 b of the service coil spring 7 and the high speed coil spring 8 are narrowed upward. It is held in contact with the two ridge lines. According to the above configuration, the governor spring 6 is operated by shifting the speed control lever 5.
When the direction of the axis changes from the x direction in the idling operation state to the x 'direction in the rated operation state, the engagement / contact state of both hooks in the hook engagement hole 18 does not change, and the engine Variations in the number of rotations can be eliminated. Further, since a single hook engaging hole 18 is formed in the speed control lever 5, the assembly of the two lower end hooks 7b and 8b becomes easier as compared with the previously proposed example. In addition, since the dimensions of the two coil springs are the same as those of the conventional example and the design does not need to be changed, the conventional two coil springs can be used.

That is, FIG. 3 (A) shows a state in which the engaged portion 9 formed of an independent member is attached to the vicinity of the lower end of the high-speed coil spring 8, and FIG. 3 (B) and FIG. An engaged portion 9 is provided integrally with the coil spring 8 in the vicinity of the lower end of the coil spring 8. According to these embodiments,
Even when the speed control lever 5 is shifted, the engagement / contact state of the hooks 7b and 8b of both coil springs does not change, and variations in the engine speed can be eliminated. Further, since the lower end hook 7b of the service coil spring 7 is engaged with the engaged portion 9 provided on the high-speed coil spring 8, assembly of both coil springs becomes easy. However, in these embodiments, the dimensions of both coil springs need to be changed in design.
