騒音の増大、有害排出ガスの増加という欠点を有
する。 As seen in Japanese Patent Application Laid-Open No. 55-25530, the idle adjustment mechanism of the carburetor allows the general user to freely adjust the adjustment part, so it is possible to set the idle speed optimally adjusted at the factory or at the dealer. , general users can readjust them at will. As a result, fuel was wasted due to improper adjustment of idle speed.
This has the drawbacks of increased noise and harmful exhaust gases.

があつた。 In order to eliminate this problem, Utility Model Application Publication No. 56-133933 covers the adjustment screw with a case formed integrally with the carburetor body and closes the case after adjustment to restrict idle rotation adjustment by general users. is proposed. However, according to this method, the design of the carburetor body had to be significantly changed in order to form the case on the carburetor body, and there was a problem that it could not be applied to products already on the market.

る。 An embodiment of the present invention will be described below with reference to FIG. Figure 1 is a partially enlarged view of the carburetor, where 1 is the carburetor body, 2 is the throttle valve, 3 is the throttle valve shaft,
Reference numeral 4 denotes an adjustment lever which is configured to move simultaneously with the throttle valve shaft 3. 5 is an adjustment screw, which is fixed by a spring 6. Reference numeral 7 denotes a case, which is screwed to the carburetor main body 1 by the adjusting screw 5 so as to cover the adjusting screw 5. Reference numeral 8 denotes a claw attached to the case 7, which engages with a pin 9 on the carburetor main body 1 so as not to rotate. A plug 10 is press-fitted into the case 7 after adjusting the adjusting screw 5.

とができる。 In the embodiment configured as described above, when the plug 10 is press-fitted after adjusting the idle speed with the adjustment screw 5 at the factory or at the dealer, the case 7 is connected to the pin 9 that is integrated with the carburetor main body 1.
Since it is fixed by the claw 8 attached to the case 7, adjustment by general users can be prevented.
第２図は、本考案による他の実施例を示すもの
で、調整ねじ５の一部を切り欠いて、プラグ１０
の一部と係合するように構成されている。 FIG. 2 shows another embodiment according to the present invention, in which a part of the adjusting screw 5 is cut out and the plug 10 is
is configured to engage a portion of the

動分だけ修正することも可能である。 In the embodiment configured as described above, when the plug 10 is press-fitted so as to engage with the adjusting screw 5 after adjusting the adjusting screw 5, the adjusting screw 5 also moves by the angle θ determined by turning the case 7. They can be turned at the same time, and it is also possible to correct engine rotation fluctuations before and after wrapping.

付けできる。 As described above, according to the present invention, readjustment by general users can be restricted with a simple structure without major design changes to the carburetor. Additionally, since the case is attached with adjustment screws, conventional models already on the market can be retrofitted.
