This type of conventional antenna arm mounting bracket A is
For example, as shown in FIGS. 6, 7, and 8, a couple of stay grips 21 and 21 are integrally protruded from both ends of an arm grip 2 that is fitted into the arm 1 of the antenna B. It consists of a mounting bolt 23 and a wing nut 24 that are inserted into the bolt hole 22 of the gripping part, and the connector is press-formed from a thin metal plate in the shape shown in FIG. 7 in order to provide appropriate elasticity and reduce costs through mass production. Then, fit the arm gripping part 2 into the arm 1, and attach the pair of stay gripping parts 21, 21.
sandwich the end 7 of the U-shaped stay 6 with the ends 7 of the stay.
and the mounting bolt 23 inserted into the stay gripping part 21
The wing nut 24 is tightened to integrally connect the arm 1 and the U-shaped stay 6.

However, the mounting bolt 23 is attached to the end 7 of the U-shaped stay 6 and the pair of stay grips 21, 21 that sandwich this.
When tightening the wing nut 24 attached to the bolt head 25 and the nut 24, the pair of stay gripping parts 21, 21 open into a V-shape due to their elasticity.
At the same time, the bolt hole 22 engages with the thread 26 of the mounting bolt 23 as shown in FIG. For this reason, the complicated and cumbersome operation of tightening the wing nut 24 while holding down the mounting bolt 23 after removing the jamming has to be repeated, resulting in the drawback that the tightening operation cannot be performed smoothly.

In order to solve the above-mentioned problems, the antenna arm mounting bracket of the present invention has a pair of stay grips that protrude from both ends of the arm grip that is fitted into the antenna arm, and one of the stay grips is attached to the base of the mounting bolt. A locking hole that engages with a locking protrusion formed in the retainer is provided, and a curling hole having a thickness larger than the thread pitch of the mounting bolt is formed in the other stay gripping portion.

When the connectors are fitted with the arm grips to the locations where both ends of the U-shaped stay are to be attached on the antenna arm, the ends of the U-shaped stay are sandwiched between the pair of stay grips, and the mounting bolts are inserted between the stay ends and the pair of stay grips. At that time, the mounting bolt is inserted from the locking hole side, so the locking protrusion at the base of the mounting bolt engages with the locking hole to prevent the bolt from rotating, and the threaded part is inserted into the locking hole. Since it is supported by a curling hole that is thicker than the pitch, the screw will not get caught in the curling hole. Therefore, the wing nut attached to the screw end can be screwed in continuously to the end without holding down the mounting bolt.
The antenna arm and the U-shaped stay can be connected easily and quickly.

Embodiments of the present invention will be described with reference to the drawings. 1st
In the figures and FIG. 2, an arm gripping part 2 to be fitted into the antenna arm 1 has a cylindrical part 3 that follows the external shape of the antenna arm 1, a plurality of anti-rotation protrusions 5 protruding from its inner peripheral surface part 4, and The stay gripping portions 8, 8 for holding the end portion 7 of the U-shaped stay 6 are integrally protruded, and the pair of stay gripping portions constitute a connector. The pair of stay gripping parts 8, 8 have a shape that follows the outer shape of the stay end 7, and one stay gripping part 8 has a square hole 11 into which a corner 10 formed at the base of the mounting bolt 9 is fitted. A curling hole 12 is formed in the other stay gripping part 8 so as to face the square hole 11.

体的に連結することができる。 Since this embodiment has the above-described configuration, the arm gripping part 2 is fitted into the U-shaped stay end attachment position of the antenna arm 1, and the pair of stay gripping parts 8, 8 are used to
When the end 7 of the shaped stay 6 is held, the mounting bolt 9 is inserted into the through hole of the stay end 7, the square hole 11 of the pair of stay grips 8, and the curling hole 12. In this case, the mounting bolt 9 is inserted from the square hole 11 side, the corner portion 10 of the mounting bolt 9 is fitted into the square hole 11, and the wing nut 15 is attached to the threaded portion 14 inserted into the curling hole 12. Therefore, in this installed state, as shown in FIG. 2, the pair of stay gripping parts 8 partially abuts the bolt head 16 and wing nut 15 due to their elasticity, but the mounting bolt 9 rotates in the square hole 11 of the stay gripping part 8. Since the thickness of the curling hole 12 is larger than the thread pitch of the mounting bolt 9, the curling hole 1
2 and the screw 14 are not caught. Therefore, the stay gripping parts 8, 8 are attached to the bolt head 16 and wing nut 15.
Even if the antenna arm 1 and the U-shaped stay 6 are in partial contact, just by tightening the wing nut 15, the antenna arm 1 and the U-shaped stay 6 can be reliably connected integrally.
