Description of the Related Art A conventional universal pipe joint of this kind generally has a fitting portion formed by bulging a spherical end portion of one joint body, and one joint body at the end portion of the other joint body. There is known a structure in which a spherical adapter fitted to a fitting portion of a body is connected.

きない問題があった。In the universal pipe joint of this structure, the direction can be changed in any direction. However, if the angle formed by one joint body and the other joint body is set to about 15 ° or more, the adapter is opened at the fitting portion. There was a problem that it could not be dealt with when the drain pipe route had a bending angle of 15 ° or more because it hits the edge and the adapter easily comes off.

自在管継手が得られなかった。In the conventional pipe joint having the structure described in Japanese Patent Application Laid-Open No. 1-18269, when the inclination angle of the end face of the joint increases, the end face shape becomes an elliptical shape having a large difference between the major axis and the minor axis. Therefore, the opening surface is less likely to be a perfect circle,
Since a step is formed on the joint end face, a universal pipe joint with a large bending angle cannot be obtained.

れに応じて調節でき、配管作業が容易にできる。According to the first aspect of the present invention, the first and second joint bodies are linearly rotated by rotating the first and second joint bodies in directions opposite to each other in the circumferential direction. When connecting a drainage pipe system or the like that can be bent to a height difference or has a horizontal deviation, it can be adjusted according to the height difference and the horizontal deviation, and piping work can be facilitated.

体内を円滑に流れる。Further, since the inclined end face openings of both joint bodies are perfect circles in which the major axis viewed from the direction perpendicular to the inclined planes of the end faces is matched with the minor axis, the ends with the first and second joint bodies are connected. Since no recessed recess is formed in the portion, the first and second
When the bending angles formed by the first and second joint bodies are adjusted by slidingly rotating the end surfaces of the first and second joint bodies with each other, the joint end surfaces are formed at any positions of the rotation angles of the first and second joint bodies. No step is formed in the joint, and both joint bodies are connected to the inner peripheral surfaces of the first and second joint bodies from the end face between the major axis and the minor axis of the opening end face by a gentle curved line or a straight line, and drainage is performed. Flows smoothly in both joints.

And the second joint body can be slidably coupled to each other without coming off,
The ease of assembly is improved, and the second joint body can be connected to the first joint body in a liquid-tight manner.
