如く形成される。すなわち頭部５Ｃは長円形をしており
その巾りは２本のアーム部材２Ａ 、２Ｂの間＠Ｈより
小であシ１かつその長さＬは間隙Ｈより充分大とするも
のである。Reference numeral 1 indicates a part of a carburetor body that constitutes a carburetor formed of plastic material, and two arm members 2A and 2B having a gap H from one side of the carburetor body.
A fitting hole 3 is formed corresponding to the arm members 2A and 2B that protrude and extend, and a first hole is formed on the side of the fitting hole 3.
The four passages and the second passage 4B are open, and at the bottom there is a third passage.
Passage 40 opens. And in the fitting hole 3 with the first.
A horizontal passage 5A and a third passage 4 that connect the second passages 4A and 4B.
Vertical passage 5B that connects to C and also connects to horizontal passage 5A.
A fixing member 5 having a jet function and having a hole therein is fitted and arranged. The head portion 50 of the fixing member 5 is particularly formed as follows. That is, the head 5C has an oval shape, the width of which is smaller than the gap between the two arm members 2A and 2B, and the length L of the head 5C is sufficiently larger than the gap H.
さらにまた気化器本体１０Ａ面よりアーム部材２Ａ２Ｂ

５の突出寸法４に比較して小とするものである。Furthermore, the arm member 2A2B from the side of the carburetor main body 10A
The gap up to the bottom surface of the carburetor body 1 is made smaller than the protrusion dimension 4 of the fixing member 5 from the A side of the carburetor body 1.
かかる如き徘造をなす固着部材５を気化器本体１に固着
する方法について次に述べる。A method for fixing the fixing member 5 having such a floating structure to the carburetor main body 1 will be described next.
まず固着部材５を嵌合孔３内に嵌入する。この時固着部
材５の頭部５０は第２図の２点鎖線の如き状態にあり、

横通路５人は気化器本体ｌの第１．第２通路４Ａ４Ｂと
連通状態にないものである。First, the fixing member 5 is fitted into the fitting hole 3. At this time, the head 50 of the fixing member 5 is in a state as shown by the two-dot chain line in FIG.
In such a state, the head 5C#'i arm member 2A2B
Since it is within the gap H, it is not subject to any restrictions by the arm member 2A2B. In addition, in such a situation, five people in the company's side passage were in the first position of the main body of the carburetor. It is not in communication with the second passage 4A4B.
次いでかかる状態より第２図の実線で示すように９０度

5B, and in this state, the IDK from the A side of the carburetor body 1 to the bottom of the arm member 2A2B is fixed to the protruding dimensions of the fixing member 5 from the A side of the carburetor body 1. Since it is relatively small, the fixing member 5 can become fixed to the carburetor main body 1 by receiving the bending force of the arm member 5A5B. In such a state, five people in the horizontal passage of the fixing member 5 are attached to the first side of the carburetor main body 1. 2nd aisle 4A
It is in communication with 4B.

のである。As described above, according to the method for fixing the fixing member in a plastic vaporizer according to the present invention, the vaporizer main body and the float chamber main body that form the vaporizer are made of plastic material, and the arm member is integrally attached to the vaporizer. At the same time, a fixing member was arranged corresponding to the arm member, and by rotating the fixing member, the bending of the plastic material of the arm member exerted a force to fix the fixing member to the carburetor. The fixing work can be done by simply rotating the welding machine (there is no need to invest in special equipment such as a welding machine, and the work time can be simply rotated), making it possible to provide an extremely simple and inexpensive fixing method.
また第３図に示す如く固着部材５の頭部５０の下面に鍔
