ストに反映する。2. Description of the Related Art A gas pipe of this kind is generally made of a copper pipe or the like, and usually has a structure in which a nozzle of another part is joined to the tip of the pipe by brazing. Therefore, at least two parts, ie, a copper pipe and a nozzle, are required. In the process, an operation for combining these two parts is naturally necessary, and the result is reflected in the cost.

However, in the nozzle device, the end of the pipe is squashed flat to form a closed portion, and the nozzle hole needs to be opened almost at a right angle immediately before the closed portion. For this reason, there is a problem that it cannot be applied to the nozzle in the axial direction of the pipe.

手段を有する（図１参照）。DETAILED DESCRIPTION OF THE INVENTION A conduit for a gas appliance according to the present invention comprises:
One end is connected to the gas source side and the other end is connected to the combustion unit side, so that the gas supplied from the gas source side is supplied to the combustion unit side. The gas source side and the combustion part side mean the upstream side and the downstream side, respectively, and do not indicate specific parts. Therefore, the conduit body 10 is formed of a tubular material (pipe) capable of transporting gas, and the gas source side member 2
1 and means for positioning the connection with the member 22 on the combustion section side (see FIG. 1).

（ノズル）を形成する手段である。At the other end of the conduit body 10, that is, at the tip end on the combustion section side, a nozzle 11 having a small cross-sectional area is formed to eject gas in a direction substantially parallel to the tube axis.
The nozzle 11 is formed by drawing the tip of the conduit body 10. The drawing process is a means for forming an end opening (nozzle) smaller in diameter than the pipe main body by plastically deforming the material using a die.

It is fixed by a suitable holding means and pressed against the end of the tube while rotating the die 30 from the axial direction. The die 30 has a molding surface whose cross-sectional area gradually decreases from a large-diameter portion 31 substantially equal to the tube outer diameter to a small-diameter portion 33 that becomes a nozzle via a tapered inclined portion 32. The inner diameter A of the nozzle portion is squeezed slightly smaller than the target size (step III), and after forming the outer shape, a pin 34 having the target diameter is inserted through the portion of the inner diameter A to form a nozzle opening 35 with a constant inner diameter ( Step IV).

The engaging means 12 for positioning the nozzle 11 is formed on the outer surface of the nozzle 0 by plastic working. The engaging portion is a positioning means for the member 22 described above, and is indispensable for determining a mounting position of the nozzle 11 with respect to the member 22. The engaging means 12 is also formed by plastically processing the conduit body 10 in the same manner as the nozzle 11, for example, by fixing the end of the conduit body 10 with a clamp 36 and fixing the conduit body 10 with a clamp 37. The end portion fixed by the clamp 36 can be formed in a bulge shape by a method of pressing the end portion in the axial direction (see FIG. 4).

The second engaging means 14 may have a bulge shape similar to the engaging means 12 for determining the nozzle position. In the case of the embodiment, the one end 13 of the conduit main body 10 is also drawn into a cylindrical shape having a slightly smaller diameter than the main body.
