部３ｂとされる。Similarly, the narrow end 1b of the base metal 1 is bent so as to come into contact with the other end 2b of the insertion member 2, and is made to protrude into the center hole of the insertion member 2, and as shown in FIG. A protrusion 12 is formed which is bent into the center hole of the member 2 and projects into the center hole of the insertion member 2 . As a result, both protrusions 11 of the base metal 1
．． The inner periphery of the insert member 2 is a vertical hole 3a, and the inside of the insertion member 2 is a groove 3b.
次いで、横穴形成工程として、地金１及び挿入部材２に
横穴３Ｃを貫設する。Next, as a horizontal hole forming step, a horizontal hole 3C is formed through the base metal 1 and the insertion member 2.
こうして、地金１及び挿入部材２により目玉部が形成さ

。In this way, the eyeball portion is formed by the base metal 1 and the insertion member 2. This eyepiece part is made by brazing a pipe part similar to the conventional one shown in FIG. 8 into the side hole 3C, and brazing a joint part similar to the conventional one to the other end of the pipe part to form the eye joint. In this joint as well, the nipple is inserted into the hose as in the conventional case, and the hose, nipple, and sleeve are integrally connected by reducing the diameter of the sleeve. In addition, a bolt having a flow path inside is inserted into the vertical hole 3a of the eyepiece through a copper washer, etc., and the bolt is screwed into the part to be attached which has a flow path, so that the eyelet is attached to the part to be attached. combined with the section. Then, the fluid in the hose passes through the nipple and the pipe portion, and flows from the side hole 3C through the groove portion 3b into the flow path of the attached part through the flow path formed in the bolt.
したがって、この製造方法では、従来のように単一の地
金から切削加工で縦穴と内部空間とを設けることにより
目玉部を形成する方法よりも、容易にかつ安価に目玉部

金１の軸方向端面が確実に互いに平行な座面とされ、使
用時において好適なシールを得ることができる。Further, in this manufacturing method, both ends 2a and 2b of the insertion member 2 are
Since the protruding portions 11 and 12 are formed by bending both ends 1a and 1b of the base metal 1 so that they come into contact with the base metal 1, the axial end surfaces of the base metal 1 are reliably set as bearing surfaces parallel to each other, making it easy to use. A suitable seal can sometimes be obtained.
（実施例２）
実施例１の製造方法では地金１の両端部１ａ、１ｂを挿
入部材２の中心孔内まで屈曲させて突出部１１．１２を
形成したが、第７図に示すように、地金１の両端部１ａ

曲させるのみで突出部１３．１４を形成することもでき
る。この場合には、両突出部１３．１４の端部が縦穴４
ａとされる。(Example 2) In the manufacturing method of Example 1, the protrusions 11 and 12 were formed by bending both ends 1a and 1b of the base metal 1 into the center hole of the insertion member 2, but as shown in FIG. , both ends 1a of the base metal 1
, 1b can also be formed by simply bending the ends 2a, 2b of the insert member 2 so as to abut them. In this case, the ends of both protrusions 13 and 14 are connected to the vertical hole 4.
It is considered a.
なお、上記実施例１．２の製造方法では突出部を形成後
、地金１及び挿入部材２に横穴３Ｃを貫設したが、突出
部の形成前に地金１及び挿入部材２にそれぞれ横穴を貫
設しておくことも可能である。In addition, in the manufacturing method of Example 1.2, the horizontal hole 3C was formed in the base metal 1 and the insertion member 2 after forming the protrusion, but the horizontal hole 3C was formed in the base metal 1 and the insertion member 2, respectively, before forming the protrusion. It is also possible to provide a through-hole.
