First, the method of mounting on the vehicle and the method of using the antenna rod will be described. As shown in FIG. 7, an example of mounting on the rear window glass surface of the vehicle (this is an example, there are other vehicle parts, etc. On the glass surface. ”), The push button provided on the outlet base is operated to release the connection between the outlet base and the plug base of the antenna base,
Attach the outlet base to the glass surface. Specifically, double-sided tape on the glass surface (an example, other adhesive,
It may be attached. The same shall apply hereinafter). At this time, the flexible mounting plate conforms to the curved surface of the glass surface and is securely mounted, and by mounting the flexible mounting plate, the outlet base is mounted on the glass surface. Therefore, when the plug base of the antenna base is inserted into the outlet of the outlet base, the antenna base and the antenna rod holding portion / antenna rod are attached to the outlet base, and thus the antenna is attached to the glass surface. However, when pulling out and rotating the antenna rod and the antenna rod holding portion, pay attention to the equipment of the vehicle and the antenna rod holding portion and the antenna rod so as not to go out of the vehicle width.

Since the antenna base thus mounted is rotatably mounted on the outlet base, the direction of the antenna rod can be freely changed.
Therefore, when changing, for example, the tightening tool (which will be described with a fixing screw) is unscrewed, the connection between the outlet base and the antenna base is released, and the antenna base is changed to an appropriate position. After that, when the fixing screw is screwed in, the antenna base is fixed at the changed position, so that the antenna rod provided on the antenna base is extended in a desired direction. Of course, the antenna base can be freely attached to and detached from the outlet base at the changed position.

Next, as shown in FIG. 8, in an example of mounting on a roof side surface of a vehicle (an example of another vehicle part, not limited thereto), the mounting is performed in the same manner as the above-mentioned glass surface, but the antenna rod holding portion and the antenna are mounted. Be careful not to let the rod go out of the car width. Specifically, after attaching the outlet base, the plug base of the antenna base is inserted into the insertion port of the outlet base. Then, by rotating the antenna base through screwing back and screwing in the tightening tool, and confirming that the antenna holding portion and / or the extended antenna rod are within the vehicle width, the antenna is used. . Especially when mounting on the roof side surface, pay attention to the extension of the extended antenna rod outside the vehicle width.

It should be noted that the antenna can be freely attached to other parts of the vehicle or accessories to the vehicle, and is not limited as long as the above-mentioned legal problems are cleared.

Next, the angle adjustment (oscillation) of the antenna rod
First, as shown in FIG. 5 and FIG. 10, the angular position (oscillation) of the antenna rod is moved by the above-described operation and procedure while the antenna base is attached to an appropriate portion of the vehicle body via the outlet base. When adjusting the (moving position), the locking (engagement) relationship between the claw piece of the lock body formed of the spring material provided on the antenna base and the concave portion of the cam provided on the antenna rod holding portion is released. However, specifically, the angle of the lever is changed by holding the antenna rod holding portion. That is, the claw piece of the lock body composed of the spring material provided on the antenna base is pulled out from the concave part of the cam provided on the antenna rod holding part, and then the claw piece rides over the convex part of the cam and fits into another concave part. To meet. The angular position of the antenna base is determined by the engagement of the other recess and the claw piece. The claw piece is made of a spring material, and has a structure that securely passes over or rides over the uneven portion of the cam and is locked, and the angle of the antenna rod depends on the positional relationship of the concave portion. The position is determined.
