Japanese Patent JP7340851

B2

To provide an insulation joint which reduces components, is easy to be assembled, reduces cost of manufacture and is hard to be damaged.SOLUTION: In a joint body (2), a flange part (17) whose diameter is expanded is formed in its end portion, and a cap nut (13) is inserted from an opening whose diameter is larger than that of the flange part (17) into the joint body (2) by forming the opening in its head portion. An insulation member (14) is formed in a ring shape which is cut partially. An annular groove part (23) is formed on an inner peripheral surface of the cap nut (13), and the insulation member (14) is accommodated in the annular groove part (14). When sliding the cap nut (13), an end face of the insulation member (14) is brought into surface contact with an end face (18) of the flange part (17) and locked, such that the cap nut (13) is prevented from being pulled out of the joint body (2). The insulation member (14) is formed in such a manner that the cross-sectional shape is made rectangular, and a wall surface (24) of the annular groove part (14) and the end face (18) of the flange part (17) are formed in a vertical surface with respect to an axis of the joint body (2).SELECTED DRAWING: Figure 1
