けによりろう付は部２０１．２０２を形成して、全体を
一体的に固定する方法が採用されている。Conventionally, such eye joints have been manufactured by cutting the entire joint. However, since there is a lot of material loss and a lot of man-hours, in recent years, the eye part, pipe part, and joint part are each formed by cutting, etc., and then the brazed parts 201 and 202 are formed by brazing, and the whole is integrated. A method of fixing is used.

困難である。また、目視だけでシール性が得られている
かどうかを検査することは一層困難である。したがって
目玉継手のように高いシール性を必要とする部品の場合
には、ろう付は後の検査工数が多大となっていた。However, in the method of joining by brazing, it is difficult to inspect whether or not the parts are reliably brazed just by looking at them. Moreover, it is more difficult to inspect whether sealing performance is obtained only by visual inspection. Therefore, in the case of parts that require high sealing performance, such as eye joints, brazing requires a large number of inspection steps.
本発明はこのような事情に鑑みてなされたものであり、

強く圧接されるとともに、係合凹部２２の内周面が係合
突部１５の外周面に圧接されて両者が確実に係合する。In the 1" ball joint of this embodiment, the eye part 1 and the pipe part 2 are connected using two molds 8 shown in FIG. This is done by forming the small diameter portion 21 and the engagement recess 22 in the pipe portion 2 by rolling. This mold 8 has a semi-cylindrical shape so that when two molds are overlapped, a cylindrical cavity having an inner diameter smaller than the sum of the outer diameter of the neck portion 14 and twice the wall thickness of the pipe portion 2 is formed. An inner peripheral surface 81 and a semicircular groove 82 for forming the engagement recess 22 are formed. That is, the neck 14
The small diameter portion 2 formed on the outer circumferential surface of the neck portion 14 is strongly pressed against the outer circumferential surface of the neck portion 14, and the inner circumferential surface of the engaging recess 22 is pressed against the outer circumferential surface of the engaging protrusion 15 to ensure that the two are firmly connected. engage.
このため、目玉部１とパイプ部２とは高いシール性を確
保して確実に結合される。Therefore, the eyepiece part 1 and the pipe part 2 are reliably connected to each other while ensuring high sealing performance.
したがって、本実施例の目玉継手では、パイプ部２の固
定にろう付けが不要となり、検査−■−数の低減を図る
ことができる。Therefore, in the eye joint of this embodiment, brazing is not required to fix the pipe portion 2, and the number of inspections can be reduced.

きる。Further, the method for forming the four engaging portions 22 is not limited to the rolling method using a die described in "-". For example, after fitting the pipe portion 2 in which the engagement recess 22 has been formed in advance by bulge pressure onto the outer peripheral surface of the neck portion 14, the outer peripheral surface of the pipe portion 2 is caulked to reduce the diameter.
Moreover, the outer circumferential surface of the engagement recess 22 can also be compressed in the axial direction.
