ても接着による管の接続を行えるようになる。As described above, in the exchange joint 21, since the procedure of moving the pipe 20 inserted into the deep receiving port 22 in the reverse direction after insertion is performed, a method of applying the adhesive and then inserting the pipe is adopted. Although it could not be done, by injecting the adhesive from the adhesive injection port 24, it becomes possible to connect the pipe by bonding at the exchange joint 21 as well.
