た。 As shown in FIG. 4, the conventional connecting cap nut has a screw 13 on the inner circumferential surface of an enlarged diameter hole cylindrical wall 12 on the tip side of a main body 11 constructed by cutting a metal bar material. were integrally provided, and a cylindrical body 14 was integrally provided protruding from the back side. Therefore, a large number of cutting operations are required, resulting in a decrease in productivity, and at the same time, an increase in the weight of the product. In addition, during installation and use, vibrations from the engine or machine interfere with the wall of the insertion hole, causing cracks and breakage on the peripheral surface of the pipe located near the rear edge of the wall of the insertion hole. This was problematic.

なることを特徴とするものである。 The purpose of the present invention is to solve the above-mentioned problems by simple injection molding with a simple structure, and furthermore, by integrally configuring the screw hole part and the retaining wall part, it is possible to solve the problem when tightening the screw to the mating connection part. By providing a cap nut for connecting the end of a small diameter metal pipe according to the present invention, the cap nut for connecting the end of a small diameter metal pipe according to the present invention solves the problem extremely effectively by eliminating the problem of The bottom of the threaded hole passing through the joint body is made of a stepped press engagement surface, and the back side of the metal joint main body is provided with a hanging wall on the outer circumferential side and an annular groove on the back side. The cylindrical body is formed by injection molding of a resin material and has an insertion hole formed through the cylindrical body, and the distal end side of the cylindrical body is fixed to the annular groove by casting to form a continuous structure. .
以下、本考案の実施例を第１図乃至第３図につ

体１に連設構成されたものである。 The metal joint main body 1 has a stepped press engagement surface 3 at the bottom of a screw hole 2 penetrating through the shaft core, and has a hanging support wall 4 on the outer circumference side and an annular groove 5 on the back side. A screw hole 2 is provided on the back of the joint body 1.
The cylindrical body 6 having an insertion hole 7 extending coaxially therewith is formed by length molding from a resin material, and its distal end is fixed to the annular groove 5 of the joint body 1 by casting. It is constructed in series.

きるものである。 As described above, according to the present invention, the metal joint body 1 integrally includes the screw hole 2 and the hanging wall portion 4.
The cylindrical body 6 made of resin material is injection molded with the resin material, and at the same time, the tip side thereof is fixed by casting to the annular groove 5 to form a continuous structure, which greatly reduces the number of cutting operations and achieves mass productivity. On the other hand, it not only reduces the weight of the product, but also enables connection to the threaded part of the mating metal base, and is particularly effective against vibrations caused by an engine or machine during installation and use. Since the insertion hole 7 sufficiently absorbs interference, it prevents cracks and breakage of the circumferential surface at this interference part on the piping side, and at the same time prevents problems when tightening the screws during connection. It is something that can be done.
