解決することにある。However, forming a key on the inner wall of the extension pipe has a problem that the operation is complicated and requires much time and effort. Further, since the key is formed on the inner wall of the extension pipe, the position cannot be visually confirmed by an operator. For this reason, the operation of aligning the key with the key groove is difficult, and it has to be performed by groping with intuition, which is very inconvenient. The problem to be solved by the present invention is to solve the above-mentioned problem.

5e is provided with an inclined end surface 15k which is inclined at substantially the same angle as that of 5e.
The movable member 15j slides with respect to the fixed member 15a and comes into pressure contact with the inner wall of the extended pipe 3 when they are brought into contact with each other and tightened by the screw member 17. The press-contact of the movable member 15j to the extended pipe 3 prevents the former from coming off from the latter, and the extended pipe 3
The extension side member 15 is fixed to the end. In the pressed state, both the outer walls of the fixed member 15a and the movable member 15j are in contact with the inner wall of the extension pipe 3 by 25 to 50%.
Is formed in such a shape as to abut at a ratio of. As shown in FIG. 6, a slide groove 15m is formed on the open end surface of the movable member 15j. The slide groove 15m is formed so as to receive the nut member 17n included in the screw member 17 so that the nut member 17n cannot rotate and can be slidably supported.

溝１５ｍが形成されている。The reason for this is that the nut member 17n is first made non-rotatable to facilitate the work at the time of tightening. Further, since the movable member 15 is slidable, a displacement (see FIG. 8B) occurs between the axis of the movable member 15 and the axis of the fixed member 13 as the movable member 15 slides. Is allowed. That is, if there is no tolerance for the deviation, an extreme bending stress acts on the screw member 17, so that the bending stress is released. Therefore, the slide groove 15m is formed so as to slide in a direction in which bending stress can be released.

より、披延長パイプ３の延長作業を完了する。(Attaching Method of Pipe Connecting Member) FIGS. 2 to 4
The method of attaching the pipe connecting member 11 will be described with reference to FIG. First, each member is temporarily assembled in the positional relationship shown in FIG. Next, the pipe extension member 11 which has completed the temporary assembly
Is inserted into the hollow portion 3 of the extension pipe 3 as shown in FIG. After the insertion, the head member 17t of the screw member 17 is rotated by a tool to pull the nut member 17n to be screwed together, whereby the movable member 15j is fastened to the fixed member 15a. At this time, the engaging convex portion 15 is
c, and the rotation of the extension side member 15 with respect to the extension side member 13 is prevented. When the tightening is further continued, the movable member 15j slides by the action of the inclined end surfaces 15e and 15k and presses against the inner wall of the extension pipe 3. By this pressure contact, the extension side member 15 is fixed to the extension pipe 3. FIG. 3 shows the pipe connecting member 11 in a fixed state. Here, the extension side member 13 protruding from the upper end of the extension pipe 3 is inserted into the hollow portion of the extension pipe 3 'and rotated in the direction of arrow b to be screwed and fixed. Thus, the extension work of the extension pipe 3 is completed.
