いる。[Means for Solving the Problems] In order to solve the above problems, the present invention is configured such that the driving half is installed in the groove of the driving half so that its diameter can be reduced, and the driving half is fitted into the groove of the joint body by press-fitting the driving half into the joint body. In a pipe joint coupling device in which a fitting main body and a driving half are connected in a relatively rotatable and inseparable manner by an elastic ring, the elastic ring is connected to a bottom wall of a groove formed on the outer circumferential surface of the driving half. The joint body is characterized in that it has a plurality of eccentricity prevention parts and a plurality of coupling parts that fit into grooves formed in the inner circumferential surface of the joint body.
