The joint 1 is made of a synthetic resin such as a hard vinyl chloride resin, and has an enlarged diameter receiving port 11 at one end. An annular groove is provided on the inner periphery of the end of the receiving port 11,
A seal packing 3 is mounted in the annular groove. Also,
A spigot 12 is provided at the other end of the joint 1.
A flange 121 that is curved with substantially the same curvature as that of the saddle joint 2 described later is provided on the outer periphery of the second member 2.

エンゴムが好適に使用できる。The saddle joint 2 has a configuration in which a tubular portion 22 projects from the center of a saddle 21 that is curved with substantially the same curvature as the outer periphery of the main pipe 6.
1 is provided with a groove 221 into which the groove 1 is fitted. The saddle joint 2 is formed of an elastically deformable elastomer resin. Examples of the elastomer resin include acrylonitrile butadiene rubber, styrene butadiene rubber, styrene butadiene styrene rubber, styrene-isoprene-styrene rubber, ethylene-propylene rubber, and ethylene-propylene diene rubber. Rubber and ethylene-propylene diene rubber can be suitably used.

度を大きく調整することができる。In the case of the branch pipe joint of this embodiment, the flange 12 provided on the outer periphery of the spigot of the joint 1 is formed in the groove 221 of the saddle joint 2.
1 is fitted and connected. Therefore, a connection hole 61 is formed at an appropriate position of the main pipe 6, the back surface of the saddle joint 2 is pressed against the outer peripheral edge of the hole 61, and an appropriate fixing tool such as a band is wound around the outer circumference of the main pipe 6 and the saddle joint 2. And fix it. After fixing the branch pipe joint to the outer periphery of the main pipe 6 in this way,
The end of the branch pipe 7 is inserted into the pipe. At this time, since the saddle joint 2 is formed of an elastomer resin, the saddle joint 2
Is easily performed, whereby the connection angle of the branch pipe 7 can be largely adjusted.

より大きく調整できるという利点がある。The branch pipe joint shown in FIG. 2 has an auxiliary member 14 fixed to the outer periphery of the spigot 12 of the joint 1 and provided with a flange 15, and the flange 15 is provided in a groove 221 of the saddle joint 2. Fitted and fixed. In the case of this embodiment, the spigot 12 of the joint 1
The tubular portion 22 of the above embodiment is attached to the saddle joint 2 into which
Since there is no equivalent to the above, there is an advantage that the connection angle of the branch pipe 7 can be adjusted more.
