に加わってもアームB1の仮止め状態を維持でき、アーム
B1の脱落を防止できる。By fitting the fitting piece 13 into the fitting hole 30 as described above, the arm B1 is temporarily fixed to the receiving member B22. That is, the connecting tool does not need to support the arm B1 from the outside.
A state in which the connection state of the arm B1 with B2 can be temporarily maintained is achieved. The operation will be described. In the state where the arm B1 is placed on the receiving surface 16 as described above, the arm B1 is heavy at the tip side where the antenna C is attached.
When the hand is released from B1, the tip side of the arm B1 tries to lower, and the support rod mounting portion B12 tries to float. However, since the fitting piece 13 is fitted in the fitting hole 30, the lifting of the support rod mounting portion B12 is prevented by the fitting piece 13. That is, the arm B1 is temporarily fixed. Further, in the temporarily fixed state, the fitting piece 13 is press-fitted into the resilient fitting hole 30, so that the fitting piece 13 is difficult to come out of the fitting hole 30. Therefore, a small external force is applied to the arm B1 by the wind.
Even if you join the
B1 can be prevented from falling off.

材26による防水効果が向上される。Further, since the fitting piece 13 is fitted in the fitting hole 30 in a press-fitted state, the thickness of the plug member 26 is pushed toward the outer peripheral surface of the fitting portion 26a. This pushing force enhances the force with which the outer peripheral surface of the fitting portion 26a adheres to the inner peripheral surface B12c of the arm B1 and the waterproof effect of the plug member 26 is improved.

れるようにする。When the temporary fixing state has been achieved, the support rod mounting portion B12 is finally fixed to the receiving member B22. For example, the support rod mounting portion B for the receiving member B22 is fixed by the bolt 29.
Twelve fixings. In this case, since the position is determined as described above, the shaft portion 29b of the bolt 29 can be smoothly screwed into the screw hole 17b.
Can enter. Since the arm B1 is temporarily fixed as described above, it is not necessary to support the arm B1 by hand. Therefore, the operator can support his / her body by grasping the pillar A with one hand and operate the bolt 29 with the other hand, and the work can be performed safely. Through hole 27
A waterproof means such as packing is interposed between the bolt and the bolt 29 to prevent water from entering the inside of the pipe arm B1.

In order to improve the retaining force of the fitting piece 13e and the fitting hole 30e in the fitted state, the fitting piece 13e and the fitting hole 13e are provided on the front side of the fitting piece 13e. This is an example in which an engaging piece 43 protruding toward one side is provided. With this configuration, when the fitting piece 13e is fitted in the fitting hole 30e,
The engaging piece 43 engages with the engaging stepped portion 44 at the inner part of the fitting hole 30e, and the fitting piece 13e becomes difficult to come off from the fitting hole 30e. Reference numeral 45 designates a slit for facilitating the deformation of the fitting hole 30e so that the engaging piece 43 can be inserted easily. In addition, for the parts which are functionally the same as or equivalent to those in the previous figure and are considered to be redundant, the same reference numerals as those in the previous figure are appended with the letter e, and the redundant description is omitted.

効果がある。As described above, according to the present invention, when a plurality of antennas C are installed, a plurality of supporting rod mounting portions B12 of a plurality of arms B1 for supporting an antenna are provided in a coupling tool B2. The arms B1 are arranged in a fixed positional relationship by mounting them on the receiving members B22, and the antennas C mounted on the arms B1 can be arranged in a predetermined positional relationship. Moreover, the above-mentioned multiple arms
In the case of mounting B1, each arm B1 has a feature that it can be mounted one by one because the support rod mounting portions B12 of the respective bases can be individually mounted to the receiving members B22 of the coupling tool B2. This has an effect that it is possible to perform the mounting work by one worker. Moreover, the above arm B1
In the case of mounting, the mounting surface 24 of the supporting rod mounting portion B12 of the arm B1 is placed on the receiving surface 16, the supporting rod mounting portion B12 is displaced along the receiving surface 16, and the fitting piece 13 is fitted into the fitting hole 30. If combined, the arm B1 can be temporarily fixed to the receiving member B22. This means that when the support rod mounting portion B12 of the arm B1 is permanently fixed to the receiving member B22, it is not necessary to separately support the arm B1. There is an effect that can be done safely. Further, when the fitting piece 13 is fitted into the fitting hole 30 to bring it into the temporarily fixed state as described above, the receiving surface 16 is used as a guide surface, and the supporting rod mounting portion B12 is provided along the receiving surface 16. Since the fitting piece 13 can be fitted into the fitting hole 30 if it is displaced, there is an operational effect that the temporary fixing state can be achieved by a very easy operation.
