Abstract

A screw fitting section to be connected to a joint member (2) is formed on a coupling body (1), and a screw fitting section to be connected to the coupling body (1) is formed on the joint member (2). Either of the coupling body (1) and the joint member (2) has a female screw tube section (14), and the other has a shaft section (23). On the inner peripheral surface of the female screw tube section (14) is formed a female screw thread (14a) as a screw fitting section, and on the outer peripheral surface of the shaft section (23) is formed a male screw thread (23a) as a screw fitting section. Further, in the shaft section (23), an annular groove (24) having a diameter equal to or smaller than the root diameter of the male screw thread (23a) is formed between a side surface (22a) of a base section (22) and the base end of the male screw thread (23a). When the coupling body (1) and the joint member (2) are fastened together, the male screw thread (23a) enters the inside of the female screw tube section (14), and the fastening between the coupling body (1) and the joint member (2) completes exactly at the time when the base end of the male screw thread (23a) goes out of sight.
