Claims

[Scope of utility model registration request]

A universal pipe joint in which a core whose inner periphery is a socket of a first pipe and whose outer periphery is a spherical surface with a diameter D is rotatably housed in a holding part of a second pipe body. The center position O is in the range of 0.5 to 0.85 times the depth b of the socket from the opening of the socket,
and the diameter D is at least equal to the inner diameter a of the socket plus twice the retaining thickness C of the universal joint. Synthetic resin universal pipe joint with
