 In general, when a pipe is used as the handle of the tool (functional component) in the above example, processing on the functional component mounting side is not necessary, but the pipe end serving as a hand portion needs to process the cut end face of the pipe. Conventionally, there is a structure shown in FIGS. 8 to 11 as a pipe end processing structure of a pipe handle.

The conventional structure shown in FIG. 8 has a blind plug (so-called plug) 82 fitted and fixed to the inner periphery of the end of a pipe 81, and the conventional structure shown in FIG. The plug 83 is fitted and fixed, and the cut end surface of the pipe 81 can be treated favorably and easily in any of the structures shown in FIGS. 8 and 9, but both of them have a tool suspending means. There was a problem that the tools could not be suspended and supported.

Therefore, as shown in FIG. 10, a projecting piece 84 is formed integrally with the plug 83 described above, and a hanging hole 85 is formed in the projecting piece 84 so that a tool is suspended and supported. is there. However, in the conventional structure shown in FIG. 10, the projecting piece 84 does not rotate, so that the direction of suspension by the suspension holes 85 is restricted. It was necessary to attach the hanging holes 85 in such a way that the orientation of the hanging holes 85 corresponded to the posture when the tool was suspended.

In order to solve such a problem, an end structure of a pipe handle shown in FIG. 11 has already been devised. That is, a plug holder 86 is attached to the outer periphery of the end of the pipe 81 in a substantially cap shape, and a plug 90 having an annular stopper 88 and a suspension hole 89 is rotatably disposed in the plug support hole 87 of the plug holder 86. It is the structure which was done.

In the conventional structure shown in FIG. 11, since the plug 90 is configured to be rotatable with respect to the pipe 81, there is an advantage that the operability of hanging the tool is improved. Since it is fixed to 81 by gluing, screwing or caulking, there are the following problems.

That is, when the plug holder 86 is fixed to the pipe 81 using an adhesive, the plug holder 86 is detached from the pipe 81 when the amount of the used adhesive is too small, and when the amount of the used adhesive is excessive, There is a problem that the agent flows to the stopper 88 and the plug 90 cannot be rotated.

On the other hand, when the plug holder 86 is fixed to the pipe 81 by using a screw or a caulking pin, there is a problem that the number of fixing steps is increased and the fixing is troublesome. Furthermore, the plug 81 and the plug 90 are required for processing the pipe end of the pipe 81, and the number of parts is large (total of three parts of the pipe 81, the plug holder 86, and the plug 90), and the cost is high. was there.
