A case will be described in which the antenna 3 is attached to the automobile 1 using the mounting tool 4 having the above configuration. First, the fixing member 5 is assembled by attaching the supporting member 7 to the fixing member 6 with the mounting screws 15, and the convex fitting portion 24 of the rotating member 19 is fitted into the concave fitting portion 16 of the supporting member 7. The supporting body 12 and the rotating body 20 are overlapped, and then the through hole 13 of the supporting body 12 and the rotating body 2
The threaded portion 31 of the tightening screw 28 is inserted into the through hole 21 of 0, and the flat spring 29 is interposed between the screw head 34 of the tightening screw 28 and the rotating body 20, and then the nut 30 is inserted into the threaded portion 31. are screwed together to form the support body 1.
2 and the rotating body 20 are elastically tightened by a flat spring 29, and the above-mentioned fixture 4 is assembled. As a result, the engaging surface 26 of the convex fitting portion 24 of the rotating member 19 is connected to the support member 7 as shown in FIGS. 4 and 5.
is resiliently engaged with the engagement surface 18 of the concave fitting portion 16, thereby preventing the rotation member 19 from rotating relative to the support member 7. That is, the nine inclined surfaces 2 of the convex fitting portion 24
6a abut against the nine inclined surfaces 18a of the concave fitting portion 16, and the relative rotation between the convex fitting portion 24 and the concave fitting portion 16 is prevented. Next, the fastening member 6 of the fixture 4 assembled as described above is fixedly attached to the rain gutter 2 of the automobile 1 with a threaded rod 10. The attachment member 6 is attached to the rain gutter 2 by
This can be done by positioning a part of the rain gutter 2 of the automobile 1 in the fastening part 9 of the vehicle, and then tightening the threaded rod 10 to sandwich the rain gutter 2 between the threaded rod 10 and the lower collar 8b. Next, the antenna 3 is attached to the antenna support portion 22 of the mounting fixture 4, and thereby the antenna 3 is fixed to the automobile 1. In addition, the above antenna 3
The installation procedure for car 1 is an example.
This may be done in a different procedure, for example, the antenna 3 may be attached to the antenna support part 22 before the attachment 4 is attached to the automobile 1, and the attachment 4 with the antenna may be attached to the automobile 1, or the attachment member 6 may be attached to the automobile 1. The support member 7 may be attached to the fastening member 6 after it is attached to the automobile 1.

Next, a case will be described in which the direction of the antenna 3 attached to the automobile 1 is changed and adjusted as described above. First, when the antenna 3 is fixed upward as shown in FIG.
As shown in FIGS. 4 and 5, the convex fitting part 24 of the rotating member 19 fits into the concave fitting part 16 of the support member 7, and the engaging surface 26 of the convex fitting part 24 becomes concave. Fitting part 1
6, the rotation of the convex fitting portion 24 with respect to the concave fitting portion 16 is locked, whereby the rotating member 19 is fixedly held relative to the support member 7. . Next, if you want to change the direction of the antenna 3 in the above-mentioned established state, for example, if the antenna 3 gets in the way when you park it in the garage, or if you want to adjust the direction of the antenna 3 to improve signal reception, use the sixth As shown in the figure, the rotating member 19 is pulled away from the support member 7 against the spring force of the flat spring 29, and an appropriate amount of the convex fitting portion 24 is extracted from the concave fitting portion 16.
The amount of extraction is made large enough to allow the convex fitting part 24 to rotate within the concave fitting part 16, as shown in FIGS. 7 and 8. (This size may be very small since the engaging surfaces 18, 26 of both fitting portions 16, 24 are inclined surfaces.) Next, tighten the rotating member 19 against the supporting member 7. Rotate in a desired direction around the set screw 28 to change the antenna 3 to the desired orientation, and at the same time, make the engaging surface 26 of the convex fitting portion 24 face the engaging surface 18 of the concave fitting portion 16. , and then release the rotating member 19 to release the rotating member 19 from the support member 7. As a result, the convex fitting portion 24 of the rotating member 19 fits into the concave fitting portion 16 of the support member 7 by the spring force of the flat spring 29, and the engaging surfaces 18 and 26 engage with each other. This ensures that the antenna 3 is fixed in the changed orientation. If it is desired to change the direction of the antenna 3 as described above, this can be done quickly by simply pulling and rotating the rotating member 19. Furthermore, as described above, no matter which direction the antenna 3 is changed to, the direction of the antenna 3 is securely fixed when the engaging surface 26 of the rotating member 19 and the engaging surface 18 of the support member 7 are engaged. Therefore, the automobile 1 can run without support not only when the antenna 3 is upright but also when the antenna 3 is tilted sideways or diagonally upward. Further, as described above, since the antenna 3 can be rotated at a portion close to the portion where it is fixed to the automobile 1, the orientation of the antenna 3 can be easily changed from inside the automobile 1.

FIG. 9 shows a different operation method when rotating the rotating member 19 relative to the supporting member 7, in which one end of the rotating member 19 is separated from the supporting member 7 (tilting it) to make it protrude. One side of the shaped fitting part 24 is pulled out from the concave fitting part 16, and in this state, the rotating member 19 is rotated about the tightening screw 28. As a result, the engaging surface 26 of the convex fitting part 24 engages with the engaging surface 18 of the concave fitting part 16, and the rotating member 19 rotates by rising on this engaging surface 18, and then When the engaging surface 26 of the convex fitting portion 24 is opposed to the engaging surface 18 of the concave fitting portion 16 and the rotating member 19 is released, the engaging surface 26 of the convex fitting portion 24 will be released. It engages with the engagement surface 18 of the concave fitting portion 16, and the rotation of the rotation member 19 is locked.

FIG. 10 shows a different embodiment of the present application,
The press drawing angle of the convex fitting part 24e of the rotating member 19e is formed to be smaller than the press drawing angle of the concave fitting part 16e of the support member 7e.

In the case of the antenna formed in this way, when tilting the antenna, the rotating member 19e is connected to the supporting member 7.
By simply applying a force to rotate the rotating member 19e (without pulling the rotating member 19e away from the support member 7e), the engaging surface 26e will move to the engaging surface 18.
Since it floats up from e, it is easy to rotate it.

It should be noted that the same reference numerals as those in the previous figure are appended with an alphanumeric letter "e" for parts that are functionally the same or equivalent to those in the previous figure, and redundant explanations are omitted.
(Also, in the following figures and subsequent figures, the same idea is applied sequentially to alphabet f and g, and redundant explanations are omitted.) Figures 11 and 12 show another different embodiment. , the concave fitting portion of the fixing member is constituted by a regular nonagonal square hole 17f, and the structure of the tightening body is further changed. In the tightening body 27f, 35
is a holding plate, and a long hole 36 formed in the center is fitted into a threaded portion 31f of a tightening screw 28f. This holding plate 35 is prevented from coming off by a nut 30f, and a flat spring 29f is interposed between this holding plate 35 and the support member 7f. The screw head 34f of the tightening screw 28f is connected to the convex fitting portion 24 of the rotating member 19f.
The clamping body 27f is accommodated in a recess 37 formed by forming the clamping body 27f by press drawing, so that the clamping body 27f does not protrude from the surface of the rotating member 19f.

13 and 14 show that the concave fitting portion 16g of the support member 7g is configured by a fitting recess 17g in the shape of a combination of a half of a truncated pyramid and a half of a truncated cone, and the curved surface of the fitting recess 17g. 38 is the diameter of the convex fitting portion 24g when the engaging surface 26g of the convex fitting portion 24g and the engaging surface 18g of the concave fitting portion 16g are engaged.
It is formed in a size that does not interfere with the

Note that in the present application, the relationship between the convex fitting portion and the concave fitting portion is a relative matter, and in understanding the present specification, the two may be understood interchangeably.

As described above, the present invention provides a fixing member 5 having a fastening portion configured to be fastened to a vehicle.
The rotating member 19 is provided with a concave fitting portion 16 at a portion facing the rotating member 19 located on the side thereof, and has an antenna support portion 22 configured to support the antenna 3. , a convex fitting part 24 is provided on the facing part 20a facing the facing part 12a of the fixing member 5, and this convex fitting part 2 is provided with a convex fitting part 24.
4 is formed into a tapered shape so as to be able to fit into the concave fitting part 16, and the concave fitting part 16 and the convex fitting part 2 are connected to each other.
4 are provided with engaging surfaces 18 and 26 each having a shape that provides a large resistance in the rotational direction when in contact with each other, and further includes a flat plate spring 29 whose plate surface is curved. Fixed member 5 and rotating member 19
and the flat spring 29, when the convex fitting part 24 and the concave fitting part 16 are fitted together, the convex fitting part 24 and the concave fitting part 16 are connected to each other. is tightened from both sides by a tightening body 27 having a threaded rod 31 penetrated through the center of the flat spring 29. When the clamping body 27 is tightened from both sides, both the fixed member 5 and the rotating member 19 are normally attached to the flat spring 29. When applying a strong force that resists the spring force of the flat spring 29, the flat spring 29 is flattened so that both can be seen from a distance, resulting in the following effects. There is. That is, (a) When it is desired to change the inclination angle of the antenna 3 attached to the antenna support part 22, the fitting part 24 of the rotating member 19 is moved from the fitting part 16 of the fixed member 5 against the spring force of the flat spring 29. By slightly separating the tapered convex fitting portion 24 from the fitting portion 16, the rotating member 19 is rotated relative to the fixed member 5 about the threaded rod 31. This has the effect of quickly changing the inclination angle of the antenna 3.

(b) After changing the inclination angle of the antenna 3, the fitting part 16 of the fixed member 5 and the fitting part 24 of the rotating member 19
is tightened by the spring force of the flat spring 29, and as a result, the engagement surface 18 of the fixed member 5 and the rotating member 19
This has the advantage that the engaging surfaces 26 of the antenna 3 can be tightly engaged with each other, thereby preventing the rotating member 19 from rotating with respect to the fixed member 5, thereby ensuring that the angle of inclination of the antenna 3 can be maintained.
