2. Description of the Related Art Conventionally, when a plug is engaged with the end of a rod tube, a concave portion is formed in the inner surface of the original rod as shown in, for example, Japanese Utility Model Application Laid-Open No. 3-105275, and an engaging piece is formed in the plug body. And a screw body is screwed into the plug main body, and when the plug main body is fitted to the inner surface of the original rod, an engaging piece is engaged with the concave portion by screwing of the screw body. In the above structure, when the screw body is screwed and the engaging piece is engaged with the concave portion, if the fitting of the plug and the plug body is loose, the plug body is rotated together with the screw body. Therefore, there is a disadvantage that the engaging operation cannot be performed unless the screw body is screwed in a state in which the original rod and the plug main body are both held and fixed by hand, so that the operation is difficult. Conversely, when the fitting between the main rod and the plug main body is tight, it is difficult to position the engagement piece and the concave portion, and the engagement is likely to be unstable. In addition, since the screw body is engaged and fixed by screwing, the number of rotations of the screw body until the engagement and fixing is increased, and it is difficult and troublesome to fix the plug body. Further, when the plug body was removed from the former pole, it was similarly troublesome.

[0003]

The problem to be solved is that if the fitting between the main rod and the plug body is loose, the plug body is rotated together with the screw body and the engagement operation is performed. Hard to do,
When the fitting is tight, it is difficult to align the engaging piece and the concave portion, and it is easy to cause unstable engagement. Since the screw body is screwed, it is difficult to perform the fixing operation, which is troublesome.
