Description of the Related Art A conventional nozzle structure is shown in FIGS. 2 and 3, in which a nozzle 1 having a polygonal column shape having the same outer diameter as the pipe diameter and having a side length of about 5 mm is attached to the pipe 5. A nozzle 1 holding a damper 4 attached to a stove burner, or having a polygonal column-shaped portion having an outer diameter equal to or greater than that of a cylindrical portion having a length of about 10 mm, which is one step thicker than the pipe 5, is connected to the pipe 5. The configuration was such that the damper was held by the mounting and polygonal column shape part.

ではシールが不完全になるという課題を有していた。However, the conventional nozzle has a configuration in which the seal is made by surface contact between the seat surface, which is the flat portion of the nozzle, and the tip of the pipe, and a large torque is required for complete sealing. . In addition, when the flatness of the seal portion of the nozzle and the pipe is not sufficient, there is a problem that the seal is incomplete without the sealant.

にガスの噴出口８を有する。In FIG. 1, a nozzle 1 has a hexagonal column-shaped portion 2 and a screw portion 3 machined from a hexagonal column-shaped brass rod, and a stove burner (not shown) formed by the hexagonal column-shaped portion 2.
The nozzle 1 is attached to the stovepipe 5 by the screw 3. The nozzle 1 is tightened by rotating the hexagonal column-shaped portion 2 with a spanner or the like. From the root of the screw part 3 to the hexagonal prism-shaped part 2,
It has two inclined surfaces having different angles. The inclined surface a6 is formed from the root of the threaded portion 3 to the same diameter portion as the stovepipe 5, and is in line contact with the inner diameter end surface of the stovepipe 5 to seal the connection portion. To the hexagonal column-shaped portion 2. The nozzle 1 has a gas outlet 8 on the upper surface of the hexagonal column.

ができ、ノズル１の全長を短くできる。Next, the operation and action will be described. Since the outer diameter of the nozzle 1 is larger than the diameter of the screw portion 3, it is easy to handle and can be securely tightened with a small torque. It can be pressed strongly by line contact, and the sealing performance is improved. Further, even when the damper 4 goes to the stovepipe 5 at the time of assembling and tries to return, the damper 4 is not caught by the nozzle 1 due to the inclined surface b7 and is easy to assemble.
Thereby, a cylindrical portion such as a conventional nozzle can be eliminated, and the overall length of the nozzle 1 can be shortened.
