Claims

[Scope of utility model registration request]

A gasket attached to the inner surface of the end of a joint body having a plurality of ends is pressed through a nut that is threadedly engaged with the end of the joint body, and the diameter of the inner surface of the end of the nut is expanded toward the gasket. A tapered surface is provided, and a ring having an appropriate number of protrusions formed on the inner periphery and one notch is placed inside the same plane of the chi, and the pipe is pressed through the nut and inserted. In the pipe joint, the inclination angle of the tapered surface of the nut on the side that allows relative displacement between the pipe joint and the pipe is larger than the inclination angle on the side that does not allow relative displacement. A pipe joint characterized by:
