横穴１０３とが形成されている。The eyeball part 100 has a ring shape, and has a vertical hole 101 and a vertical hole 1.
A ring-shaped groove 102 formed on the inner circumferential surface of 01;
A horizontal hole 103 is formed whose axial direction intersects with the vertical hole 1 (l) and communicates the groove 102 with the outside, thereby communicating the outside and the flow path via the groove 102.
パイプ部２００は、中心穴が横穴１０３と連通するよう

運ばれる。In this joint, the nipple 300 is inserted into the hose, and the sleeve 400 is reduced in diameter to integrally connect the hose, the nipple 300, and the sleeve 400. Further, a bolt having a flow path inside is inserted into the vertical hole 101 of the eyepiece 100 through a copper washer, etc., and the bolt is screwed into a part to be attached having a flow path, so that the eyepiece 100 is covered. Combined with the mounting part. The fluid in the hose then passes through the nipple 300 and the pipe section 200,
It flows from the side hole 103 through the groove 102, through the flow path formed in the bolt, through the flow path of the attached part, and is carried to a predetermined location.

However, since there is a lot of material loss and a lot of man-hours, in recent years, the center part, pipe part, and joint part are each formed by cutting, etc., and then the brazed parts 201 and 22 are formed by brazing, and the whole is integrated. A method of fixing is used.
［発明が解決しようとする課題１
ところで目玉部１００は、上記したように縦穴１０１、
溝部１０２．１よび横穴１０３をもつ複雑な形状である

工数が多大となり、さらなる改善が求められている。[Problem to be Solved by the Invention 1 By the way, the eyeball portion 100 has the vertical hole 101, as described above.
It has a complex shape with a groove 102.1 and a side hole 103. Therefore, the number of man-hours required to form the eyeball part 100 by cutting is large, and further improvements are required.

である。[Means for Solving the Problems] The present inventors have developed an eyepiece structure that solves the above problems by forming the upper and lower halves into two parts by cutting, and then joining them together by brazing. It reminded me of joining. However, in this case, the end faces of each member are joined, so high brazing requires securing the width of the end faces in order to obtain strength. However, in this case, the outer periphery of the eyepiece becomes large, causing problems in terms of space. As a result of extensive research, the inventors of the present invention have found a shape that allows the bonding area to be expanded while maintaining the outer peripheral shape the same as before, and have completed the present invention.

を特徴とする。That is, the present invention that solves the above problems has a vertical hole into which a bolt having a flow path is inserted, a ring-shaped groove formed on the inner circumferential surface of the vertical hole, and an axial direction that intersects with the vertical hole and communicates the groove with the outside. As a result, the center hole is made up of a horizontal hole that communicates with the outside and the flow path via the groove, the pipe section has one end integrally connected to the center hole so that the center hole communicates with the horizontal hole, and A joint part coupled to the other end, and an eye joint consisting of a first bottom part having a first center hole and a first bottom part having an outer diameter smaller than the outer diameter of the first bottom part and protruding from the first bottom part. an inner cylindrical member consisting of a local part, a second bottom part having a second center hole and a first part;
an outer cylindrical member consisting of a second cylindrical part having an inner diameter substantially the same as the outer diameter of the cylindrical part and protruding from the peripheral edge of the second bottom part, the first cylindrical part being fitted into the second cylindrical part; It is characterized in that the inner cylindrical member and the outer cylindrical member are integrally joined by brazing at their contact surfaces.

いる。The feature of the present invention lies in the structure of the eyepiece, which is composed of an inner cylinder member and an outer cylinder member. The inner cylindrical member and the outer cylindrical member each include a first bottom portion and a second bottom portion each having a first center hole and a second center hole, and a first cylindrical portion and a second cylindrical portion protruding from the respective bottom portions,
A first cylindrical portion of the inner cylindrical member is fitted into a second cylindrical portion of the outer cylindrical member.

A song-shaped space surrounded by the inner circumferential surface of the cylindrical portion and the inner surface of the second bottom portion functions as a groove portion. Note that the lateral hole is provided to penetrate the first cylindrical portion and the second cylindrical portion in the radial direction. They can be formed in advance on the outer cylinder member and the inner cylinder member, respectively, or they can be bored after they are joined. In this case, alignment at the time of bonding becomes unnecessary.

ことができ、製造コストの低減を図ることができる。[Operations and Effects of the Invention 1] In the eye joint of the present invention, since the inner cylinder member and the outer cylinder member are cylindrical with an opening at one end, they can be easily manufactured by cutting or the like. Not only the end faces of the first cylindrical part and the second cylindrical part, but also the outer circumferential surface of the first cylindrical part and the second cylindrical part.
Since the inner circumferential surface of the cylindrical portion is also brazed, a large bonding area can be secured without increasing the diameter of the eyepiece, and sealing performance equivalent to that of conventional products can be secured. Therefore, according to the eye joint of the present invention, the number of manufacturing steps for the eye portion can be reduced, and manufacturing costs can be reduced.
［実施例１ 以下、実施例により具体的に説明する。[Example 1 Hereinafter, this will be explained in detail using examples.
第１図に本発明の一実施例の目玉継手の目玉部の構成を

The first cylindrical portion 12 is configured to protrude from the first bottom portion 10 on the inner peripheral side of the outer peripheral end surface of the first bottom portion 10 . Further, the outer cylindrical member 2 includes a second bottom portion 20 having a second center hole 21 and a second cylindrical portion 22 protruding from the peripheral edge of the second bottom portion 20 . The outer diameter of the first cylindrical portion 12 is substantially the same as the inner diameter of the second cylindrical portion 22, and the first cylindrical portion 12 is configured to be fit into the second cylindrical portion 22.

As shown in the figure, the end face of the first cylindrical part 12 and the surface of the second bottom part 20, the outer peripheral surface of the first cylindrical part 12 and the inner peripheral surface of the second cylindrical part 22, the end face of the second cylindrical part 22 and the first bottom part. 10 are joined by brazing to form a brazing portion 15. In this way, since the area of the brazed part 15 is large, the inner cylinder member 1 and the outer cylinder member 2 are integrally and firmly connected to form the eyepiece part. Further, the joint area between the outer peripheral surface of the first cylinder part 12 and the inner peripheral surface of the second cylinder part 22 occupies most of the total joint area, and the widths of the end faces of the first cylinder part 12a and the second cylinder part 22 are made large. Since this is not necessary, the outer diameter of the eyepiece member is prevented from increasing.

。After the inner cylinder member 1 and the outer cylinder member 2 are joined together, a horizontal hole 16 is bored through the second cylinder part 22 and the first cylinder part 12 in this eyepiece part, as shown in FIG. A ring-shaped space surrounded by the inner surface of the first bottom portion 10, the inner circumferential surface of the first cylindrical portion 12, and the inner surface of the second bottom portion 20 functions as the groove portion 17, and the horizontal hole 16 communicates with the groove portion 17 (), the groove portion 17 is the first center hole 11
and a vertical hole formed by the second center hole 21.
