Problems with the prior art: Since the number of parts is large and screw members are used to attach the sliding rod, the number of processing and assembly steps is high, resulting in poor productivity and high costs.

Means for Solving the Problems The use of screw members is eliminated and a configuration is adopted that allows assembly using a snap action.

Structure of the invention Each starting auxiliary carburetor provided in each carburetor constituting the multiple carburetor is operated by a single sliding rod connected to the plunger of each starting auxiliary carburetor. In the twin carburetor, a hollow cylindrical body formed integrally with the housing and parallel to the sliding direction of the sliding rod is provided on the side surface of the housing of each of the carburetors on the side where the sliding rod is arranged. a guide member interposed between the hollow cylindrical body and the sliding rod to form a guide surface with the sliding rod; A slot is formed for inserting the guide member from the side, and the guide member is placed over the sliding rod from the side and moved along the sliding rod to be inserted into the hollow cylindrical body. The hollow cylindrical body is molded from a flexible synthetic resin material, and is cut at one point between the outer circumferential surface that fits into the inner circumferential surface of the hollow cylindrical body and the inner circumferential surface that forms the guide surface of the sliding rod. .

Embodiment FIG. 1 is a perspective view showing an embodiment of the guide structure of a sliding rod for operating the starting auxiliary carburetor of a multiple carburetor according to the present invention, in which reference numeral 1 indicates each of the multiple carburetors constituting the multiple carburetor. The carburetor 4 is a sliding rod as in the above case, and 101 is a hollow cylindrical body integrally molded with the casing of the carburetor 1, and the sliding rod 4 is The hollow cylindrical body 101 is formed parallel to the direction.
The wall forming the slit 102 is formed with a slot 102, and the sliding rod 4 can be inserted into the inside from the side. Reference numeral 103 denotes a guide member for the sliding rod 4 which is inserted into the hollow cylindrical body 101 in the direction of the center line of the hollow cylindrical body 101 and is held therein, and is molded from elastic synthetic resin and has a groove at one end. A second locking piece 105 is integrally molded on the other end of the first locking piece 104, and the first and second locking pieces 104, 10
5 is locked by both end faces of the hollow cylindrical body 101 to prevent it from falling off from the hollow cylindrical body 101. Numeral 4-1 is an engagement means for connecting the plunger 3 of the starting auxiliary carburetor 2 and the sliding rod 4, and is integrally formed with the sliding rod 4.

2 is a side view of the guide member 103, FIG. 3 is a view taken in the direction of the arrow in FIG. 2, and FIG. 2 is a sectional view taken in the direction indicated by the - arrow in FIG. Reference numeral 103 in Fig. 2,
Reference numerals 105 to 105 indicate the same parts as in FIG.
In FIG. 3, reference numeral 106 indicates a through hole for guiding the sliding rod 4 between the outer peripheral surface of the guide member 103 and the through hole 1.
06 is cut along the entire length along a plane parallel to the center line of the guide member 103. 107 indicates the cut portion. In addition, in FIG. 2, an escape 108 is provided in the through hole 106 from the end on the side where the second locking piece 105 is formed, and a cut surface is formed with the second locking piece 5 in between. The guide member 103 can be easily inserted into the hollow cylindrical body 101. Fourth
The figure shows a procedure for attaching the sliding rod 4 to a hollow cylindrical body 101 integrally molded to the casing of the carburetor 1. FIG. 4 shows the state after the guide member 103 has been attached to the sliding rod 4. That is, the elastic guide member 103
The state after opening the cutting part 107, guiding the sliding rod 4 into the through hole 106 through the cutting part 107, and closing the cutting part 107 again is shown. Next, the sliding rod 4 is moved, for example, in the direction of the arrow 109 and inserted into the hollow cylindrical body 101, and then the guide member 1
03 along the sliding rod 4 in the direction of arrow 110 and inserted into the hollow cylindrical body 101 to complete the installation.
As described above, the second locking piece 105 of the guide member 103 has a relief 108 formed therein and is cut along both sides, so that it can be easily attached to the hollow cylindrical body 101.
It can pass through the interior, open again, and be locked to the end face of the hollow cylindrical body 101 to prevent it from falling off.

In FIGS. 1 to 4, the hollow cylindrical body 101 and the guide member 103 are illustrated as hollow cylindrical bodies whose cut shape is elliptical, but the present invention does not limit the cut shape to an ellipse. Any hollow cylindrical body having a circular, elliptical, rectangular, square or irregular cross-section may be used and is within the scope of the present invention. Further, regarding the locking means for preventing the guide member 103 from falling off from the hollow cylindrical body 101, the guide member 10
The locking pieces 104 and 105 formed at both ends of the cylindrical guide member 103 are just one example, and for example, even if grooves are provided at both ends of the cylindrical guide member 103 and elastic clips are used. It is well within the scope of this invention.

Effects of the invention The guide structure of the sliding rod for operating the starting auxiliary carburetor of the multiple carburetor of the present invention has an engaging means 4-1 that connects the plunger of the starting auxiliary carburetor to the sliding rod 4.
Even if the rods are integrally molded or connected, the sliding rod can be mounted with a snap action without requiring as many parts and man-hours as in the conventional configuration shown in FIGS. 7 and 8. 4 can be attached to the multiple carburetor from the side, which is extremely effective in reducing costs.
