In particular, in terms of strength against thermal deformation, etc., if the branch pipe 1 is made of metal, there is no problem even if the nipple portion 2 is thin. However, if the branch pipe 1 is made of synthetic resin from the viewpoint of weight reduction, the thickness of the nipple part 2 must be increased, and the work of connecting the connecting part 6 to the nipple part 2 must be further performed. I was making it difficult.

It is larger than the inner diameter of the general part other than the hose connection part (exceeding the inner diameter of the general part) and smaller than the outer diameter of the nipple part (less than the outer diameter of the nipple part), so it is different from the conventional one. The connection can be made more easily than when the inner diameter of the connecting part of a hose is made equal to the inner diameter of the general part other than the connecting part.

It is formed from rubber such as PDM, and as shown in FIG. 1, the connecting portion 16 connected to each nipple portion 12 is formed in advance to have a larger diameter than the general portion 17 other than the connecting portion 16. The inner diameter D5 of the general part 17 is the diameter of the nipple part 1 to be connected.
It is formed equal to the inner diameter D1 of No. 2.

It is smaller than 3.

等の合成樹脂から形成されている。The mold part 18 is made of a synthetic resin such as polyamide, which is the same material as the branch pipe 11, in consideration of the shrinkage rate with the branch pipe 11.

At this time, each hose 15 is pushed in until the connecting portion 16 comes into contact with the main body 11a of the branch pipe 11 so that the hooking resistance of each rib 13 becomes high.
【００２３】その後、その接続された部位を所定の金型
にセツトし、その周囲に、射出成形等によりにモールド

に各ニツプル部１２に締結することができる。Thereafter, the connected portions are set in a predetermined mold, and the molded portions 18 are formed around the connected portions by injection molding or the like, thereby firmly connecting the connecting portions 16 of each hose 15 to each nipple portion 12. can be concluded.

以上としているため、実際上支障は生じない。Further, after each hose 15 is connected to each nipple portion 12, the periphery of the connection portion is molded with the mold portion 18, so that a decrease in fastening force can be suppressed to the utmost. In addition, in the case of the example, the fastening force was 30
%, but since the fastening force itself is 1.5 times or more compared to the case where the connecting portion 16 is fastened to the nipple portion 12 using other clamps or the like, there is no problem in practice.

果を奏する。In particular, when the braided layer 15a is formed on the hose 15, the diameter of the connecting portion 16 is expanded during vulcanization to manufacture the hose 15. Therefore, in the connecting portion 16 that is vulcanized in the expanded diameter state, the braiding angle of the reinforcing yarns forming the braided layer 15a (the angle that intersects the axial direction of the hose 15)
is vulcanized while being forcibly enlarged. That is, at that time, the connecting portion 16 is vulcanized with internal stress that tends to reduce the diameter due to the braided layer 15a. As a result, when the pressure fluid flows through the flow path of the hose 15 during use after the connection part 16 is fastened to the nipple part 12, the reinforcing threads of the braided layer 15a of the connection part 16 are removed from the braided layer of the general part 17. The tensile force of the reinforcing yarn 15a acts to reduce the diameter of the connecting portion 16 in an attempt to return to the original braid angle, and has the effect of further increasing the fastening force of the connecting portion 16 to the nipple portion 12.
【００２８】そして、締結された後は、各ホース１５の

る。After they are fastened, the inner diameter D5 of the general portion 17 of each hose 15 and the inner diameter D1 of each nipple portion 12 are equal, so that the cooling water flowing through the flow path of each hose 15 and each nipple portion 12 is equal. The flow rate can be accurately ensured, and the same effects as those described in the section of the above-mentioned functions and effects of the invention can be achieved.

6 is smaller than the maximum outer diameter D3 of the nipple part 12 before being connected to the nipple part 12, and the inner diameter D4 of the nipple part 12 is smaller than the maximum outer diameter D3 of the nipple part 12, and the inner diameter D4 of the nipple part 12 is smaller than the outer diameter of the general part 14 where the rib 13 is not formed or the inner edge of the tapered surface of the tip. The case where the diameter is larger than D2 is shown. However, the lower limit of the inner diameter D4 is the general part 1 of the hose 15.
It is sufficient if the size is larger than the inner diameter D5 of No. 7 (as long as the dimension exceeds the inner diameter D5). Incidentally, as in the embodiment, the lower limit of the inner diameter D4 is set larger than the outer diameter D2 of the general part 14 of the nipple part 12 where the rib 13 is not formed, or the inner edge of the tapered surface of the tip. In this case, the connection of the hose connection part 16 to the nipple part 12 can be made easier.
