In this type of carburetor, a double-sided support or a cantilever support is adopted as a support structure for the small bench lily with respect to the carburetor main body. For example, there is a double-sided support structure shown in Japanese Utility Model Application Publication No. 57-144262. According to this, the small bench lily can be securely attached and there is little risk of loosening, but the small bench lily is supported. for at least 2
Since the main arm is provided across the intake passage, there is a problem that the intake resistance increases or the turbulence of the intake air flow becomes large, which adversely affects the distribution of the air-fuel mixture to each cylinder.

それはない。 The cantilever support structure solves this problem, but the mounting structure of the small bench lily to the carburetor body poses a problem. That is, in the case where the small bench lily is attached with a mounting screw, the attachment to the carburetor body is reliable, but the attachment structure becomes complicated, and there is a problem that the entire carburetor becomes larger. On the other hand, when the small bench lily is attached to the carburetor body by press-fitting, the mounting structure is simple and there is no risk of the carburetor becoming larger. There is a problem that the press-fit surface of the container body creeps and loosens. Utility Application No. 58-201388 (U.S. Pat.
105861), according to which the top surface of the base of a small bench lily press-fitted into the carburetor body,
Since a spring member is interposed between the air horns screwed and fixed to the upper surface of the carburetor main body, there is no fear that the small bench lily will slip out from the carburetor main body even if the press-fit surface becomes loose.

However, even with this technology, if the press-fitting surface becomes loose, the small bench lily will rotate around the base, causing an imbalance in its positional relationship with the large bench lily, changing the negative pressure applied to the main nozzle's jet port, and mixing There is a problem in that the air mixture ratio deviates from a predetermined value and the exhaust gas purification performance deteriorates. Further, since the spring member is interposed between the carburetor main body and the air horn, there is a problem that the spring member easily falls off when these three members are assembled, and it takes time and effort to assemble the carburetor. The present invention solves such problems.

のに有効である。 In this embodiment, the carburetor body 10 is made of aluminum material, and the small bench lily 20 is made of zinc material.Since zinc material has a larger coefficient of linear expansion, the carburetor body 10 receives heat from the internal combustion engine. If the temperature rises, the cylindrical part 22 at the bottom of the mounting base 22
The fitting pressure between the press-fitted part of the carburetor body 10 and the press-fitted part increases, and both members 1 are also subjected to vibrations from the internal combustion engine.
Creep is likely to occur on the press-fit surfaces of 0 and 22a, and loosening is likely to occur. However, the recess 18 and the arm 2
3, both sides 27, 27 of the leaf spring member 25 are interposed in a compressed state between the portions 23a of the plate spring member 25, so even if the press-fit surface becomes loose, rotation of the small bench lily with respect to the carburetor body 10 is prevented. Bench lily part 2
1 and the large bench lily 10 will not be out of alignment. Therefore, the negative pressure characteristics applied to the ejection port 35a of the main nozzle 35 do not change, so that the mixture ratio of the air-fuel mixture is prevented from deviating from a predetermined value. Therefore, preventing such imbalances in the mixture ratio is not only effective in reducing harmful components in the direct exhaust from the internal combustion engine, but also in exhaust treatment by installing a three-way catalyst etc. after the internal combustion engine. It is also effective in fully demonstrating the function of the three-way catalyst.
