A screw hole 8 for screwing the screw 7 is formed. In the illustrated embodiment, the mounting plate body 1 is provided with the bulging portion 9 and the nut 10 is enclosed and locked in the bulging portion 9, but other than this embodiment, for example, Needless to say, the screwing position of the screw 7 for mounting the rotating plate 3 on the mounting plate body 1 may be thickened and a screw hole may be formed in the thickened portion. In addition, a soft rubber sheet or a vinyl chloride sheet having a cushioning effect is attached to the back surface of the mounting plate body 1 so that the vehicle body can be protected. In addition, 11 in the drawing is a small screw for fixing which is screwed into the folded-back portions 6 and 6.

Next, the rotating plate 3 is capable of maintaining a parallel state with the mounting plate body 1, and a pair of support arm plates 5 and 5 vertically installed upright on both sides of the tip of the horizontal part 12. The horizontal portion 12 is formed with a through hole 13 for passing the screw 7 screwed into the screw hole 8 of the mounting plate body 1. Reference numeral 14 in the drawing denotes an auxiliary metal fitting for tightening the screw 7 to stop the movement of the rotating plate 3 or loosening the screw 7 to smooth the horizontal rotation of the rotating plate 3. As described above, the rotating plate 3 is axially attached to the mounting plate body 1 by the screw 7, and by loosening the screw 7, the rotating plate 3 pivots the screw 7 with respect to the mounting plate body 1. It can be rotated 360 ° in the horizontal direction.

The rotation block 4 is pivotally mounted between the pair of support arm plates 5 and 5 provided on the rotation plate 3 so as to be rotatable. In the illustrated embodiment, the support arm plate is used. Screws 15, 15 are inserted from the outside of each of 5, 5 and screwed into screw holes 16, 16 provided on both left and right sides of the rotary block 4. The screws 15 and 15 are designed so that their tips do not contact each other even when screwed into the screw holes 16 and 16 of the maximum rotation block 4. That is, a through hole 17 having a comparatively large diameter is formed in a portion substantially orthogonal to the pivot axis in the center of the rotating block 4, and a screw rod 18 to be described later passes through this through hole 17. The lengths of the screws 15 and 15 are adjusted so as not to hinder the insertion of the screws. Further, as shown in FIG. 2, a through hole 17 formed substantially in the center of the rotating block 4 so as to be orthogonal to the axial direction has a large diameter on the inlet side of the screw rod 18 and a small diameter on the outlet side. The boundary between the large diameter portion and the small diameter portion is a step portion 19.

The antenna base mounting bracket 2 has a large-diameter hole 21 through which the antenna base 20 is inserted, and a cylinder that can be inserted into a small-diameter portion of the through-hole 17 provided in the rotating block 4. A projecting portion 22 is provided, and a female screw that is screwed into a thread groove 23 formed on the outer peripheral portion of the distal end of the threaded rod 18 is provided in the center through hole of the tubular portion 22. Such an antenna base mounting bracket 2 has a knob 24 at the base end, and a rotation block using the screw rod 18 having the thread groove 23 formed on the outer periphery of the tip as described above, and the coil spring 25. It is attached to 4. That is, after the threaded rod 18 is passed through the winding center of the coil spring 25, the tip of the threaded rod 18 is passed through the large-diameter through hole 17 of the rotating block 4, and is inserted into the small-diameter portion of the through hole 17. The coil spring 25 is screwed onto the female screw of the tubular portion 22 of the base mounting bracket 2 and is positioned between the stepped portion 19 and the knob 24 in the through hole. Then, since the step portion 19 side of the coil spring 25 becomes the fixed side, an elastic force acting in the direction of the knob 24 acts, and the antenna base mounting bracket 2 screwed to the tip of the screw rod 18 is strongly attached to the rotating block 4 side. It is pulled and comes into tight contact with the contact surface provided on the rotation block 4. Therefore, loosen the screw rod 18 a little from the antenna base mounting bracket 2 and then push the knob 24 slightly to the rotating block 4 side against the elastic force of the coil spring 25 or hold the antenna base mounting bracket 2. The antenna base mounting bracket 2 can be tilted in the left-right direction with respect to the rotating block 4 by pulling it to the side opposite to the rotating block 4 to regulate the spring force of the coil spring 25. After the mounting bracket 2 is positioned in the left-right direction, the screw base 18 is screwed into the female screw of the cylindrical portion 22 of the antenna base mounting fixture 2 to the end so that the antenna base mounting bracket 2 is fixed to the rotating block 4. In this fixed state, it is possible to prevent the antenna base mounting bracket 2 from freely tilting even if vibration is applied to the vehicle body. That. If the concavo-convex portions 26 and 27 that can mesh with each other are radially formed on the contact surface of the rotating block 4 and the contact surface of the antenna base mounting bracket 2, the antenna base mounting bracket 2 tilts.
