To improve flushing without forming a reduced pipe part in a universal pipe joint using a flexible pipe.

This universal pipe joint 1 is composed of a shell 2 and a core 3 sliding on an inner surface of the shell 2, and a joint pipe preventing a waste material sump is formed by arranging the flexible pipe 6 over an inner diameter side base part of these shell 2 and core 3. A stopper without abutting on the flexible pipe 6 even when the core 3 maximally freely changes, is arranged in the shell 2, without forming a reduced pipe part on the pipe top side of the flexible pipe 6.
