Claims

[Scope of utility model registration request]

It consists of a coupling box, a main body, and a pipe sleeve, and the main body has a spherical outer circumferential surface, while a cylindrical insertion hole is bored inside it, and the outer diameter of the pipe sleeve is equal to that of the insertion hole. The pipe sleeve is formed to have dimensions corresponding to the inner diameter of the pipe sleeve, and the pipe sleeve is fitted into the fitting hole so as to be rotatable about the axis of the fitting hole, and a first pipe is fitted to one end of the pipe sleeve. The joint box is formed hollow, and the inner circumferential surface of the hollow portion is formed into a spherical surface having a radius corresponding to the radius of the outer circumferential surface of the main body. The above body is left in the section,
Moreover, the state in which the joint box is left in place is such that the joint box is oscillated relative to the main body about a first straight line that is orthogonal to the axis of the fitting hole in the main body, and that the joint box is perpendicular to both the axis and the first straight line. furthermore, the coupling box is provided with a connecting portion to which a second pipe can be connected; A communication groove is formed around a part of the inner peripheral surface of the pipe sleeve, and communication holes are formed in the main body, one end of which opens into the outer peripheral surface of the pipe sleeve, and the other end of which opens into the communication groove. A communication hole is formed in the joint box so that the first pipe connected to the connection part of the main body communicates with the communication groove of the main body, and on the other hand, the joint box is provided with a communication hole that is connected to the connection part of the main body. A fluid piping universal joint characterized in that a communication hole is bored through which the second pipe communicates with the communication hole of the main body.
