を防止するだめの手段を設けておく必要がある。FIG. 1 shows a longitudinal sectional side view of an example of a conventional low-speed fuel passage system for an internal combustion engine carburetor. In the figure, 1 is a carburetor throttle chamber, 2 is an inner wall surface of the intake passage of the throttle chamber 1, 3 is a throttle valve, 4 is a low-speed fuel passage formed in the throttle chamber 1, and 5 is connected to the low-speed fuel passage 4. A bypass port 6 opens at a position immediately upstream of the closed position of the throttle valve 3 on the inner wall surface 2 of the intake passage, and is inserted through an insertion hole 7 penetrating the outer wall of the throttle chamber 1 from the low-speed fuel passage 4. a plug bin whose tip portion is plunged into a fuel flow path leading to the bypass port 5;
8 is connected to the low-speed fuel passage 4 and is connected to the intake passage inner wall surface 2;
An idle boat 9 that opens immediately downstream of the closed position of the throttle valve 3 is screwed into a screw hole 10 provided in the outer wall of the throttle chamber 1 and communicates from the low-speed fuel passage 4 to the idle boat 8. An idle adjustment screw whose tip is inserted into the fuel flow path to adjust the idle fuel injection amount; 11 is an adjustment knob formed at the outer end of the adjustment screw 9; 12 is a connection between the knob 11 and the outside of the throttle chamber 1; Shows a spring stretched between the wall and the wall. After the idle adjustment screw 9 is adjusted so that the idle fuel ejected from the idle boat 8 becomes the optimum amount in the final process of manufacturing the carburetor, it is used as a means to prevent harmful operation by market operators, etc. It is necessary to set it up.
この手段として従来一般には第１図のようなりミンクキ

とにより、調整ねじ９の回動を確実に阻止するのが普通
である。Conventionally, as a means for this, a mink camp 13 is mounted on the adjustment knob 11 as shown in FIG. Normally, rotation of the adjustment screw 9 is reliably prevented by press-fitting it into a blind hole 16 formed from the outer wall surface of the throttle chamber 1.
しかし上記のような従来の調整ねじ回動阻止方式では、
上記のようなストップピン１５および盲孔１６の余分の

とが考えられる。またその対策として空気逃がし孔を設
けても、やはりコストの増大が避けられない。However, with the conventional adjustment screw rotation prevention method as described above,
An increase in manufacturing costs due to extra materials and manufacturing process waste for the stop pin 15 and blind hole 16 as described above is unavoidable. Moreover, when the stop pin 15 is press-fitted, the blind hole 1
There is a case where the compressed and high-pressure air trapped in the throttle chamber 1 causes expansion and deformation of the constituent members of the throttle chamber 1, and furthermore, when the trapped high-pressure air is exposed to high temperatures as described above. It is conceivable that an accident may occur in which the stop pin 15 is pulled out due to the expansion force and loses its intended anti-return effect. Furthermore, even if air escape holes are provided as a countermeasure, an increase in cost cannot be avoided.
本発明は上記のようなアイドル調整ねじの再調整阻止方
式の従来の難点を解決することを目的とするもので、前
掲の特許請求の範囲の欄に記載した特徴を有するもので
ある。The present invention aims to solve the above-mentioned difficulties in the conventional method of preventing readjustment of the idle adjustment screw, and has the features described in the claims section above.

が本発明による特徴をなすものである。FIG. 2 shows a longitudinal cross-sectional side view of one embodiment of the present invention, and each reference numeral 1 to 14 indicates the same target portion as in FIG. 1. In this embodiment, the stop pin 15 and its blind hole 16 as shown in the conventional example shown in FIG. The outer end side is extended to form an extension part 17 protruding from the outer wall of the throttle chamber l, and this extension part 17 is connected to the limiter camp member 13.
A feature of the present invention is that it is inserted through an insertion hole 14 provided on one side edge of the holder.

おそれもない。As is clear from the above description, according to the present invention,
The stop pin 15 as in the conventional example shown in FIG.
There is no need to provide a blind hole 16 for press-fitting, and the plug pin 6 for the bypass port 5, which is conventionally used, can be used to prevent rotation of the limiter camp 130 by simply making it a little longer, and the raw materials and manufacturing process of this type of product can be improved. Manufacturing costs can be reduced through savings and shortening. Moreover, when the plug pin 6 is inserted into the insertion hole 7, its inner tip is open into the low-speed fuel passage 4, so the first
Unlike the blind hole 16 in the conventional example shown in the figure, there is no place where the air is compressed by press-fitting the stop pin 7, etc., and therefore the air is not compressed by being confined in the blind hole 16 as in the conventional example described above. There is no risk of accidents occurring due to the expansion force of air.
