 An antenna mounting device for an automobile is generally composed of a body mounting bracket that is fixed to the body of the automobile and an antenna mounting base that mounts the antenna body.The conventional antenna mounting device integrates these components. Could not be separated. Therefore, when washing the car, twist the power supply part of the antenna body from the connector part of the antenna mounting base to remove it, store it in the trunk room, etc., and cover the exposed connector part with a waterproof cap. I was trying to prevent the entry.

However, the screw pitch formed on the inner peripheral surface of the feeding part of the antenna main body is extremely fine, and it is necessary to turn the antenna main body in a sufficient number to detach the antenna main body from the connector portion of the base, which is troublesome. There is a problem that the power supply part and the connector part are damaged if the antenna body is repeatedly attached and detached.

In order to solve such a problem, the antenna mounting base is designed so that it can be separated from the base part fixed to the body of the automobile, and the antenna mounting base can be attached to the base part while the antenna is mounted when washing the car. An on-vehicle antenna support mechanism that can be detached from the body is disclosed in Japanese Utility Model Publication No. 1-32407.

Although the antenna body 17 is removed from the connector 12 for the sake of convenience in the embodiment shown in FIG. 1, the antenna body 17 is actually always screwed to the connector 12 and is used for car washing. In order to remove the antenna mounting member 2 from the body side fixing member 1 with the antenna body 17 still attached, the handle portion 11 of the operation lever 5 is grasped and turned in the arrow direction of FIG. Then, the holding cam surface 6 of the operating lever 5 moves away from the contact surface 16 formed on the protruding portion 14 of the antenna mounting member 2 to the position shown in FIG. 2 or 3, and the antenna mounting member 2 is locked. Since it is released, the antenna mounting member 2 can be easily taken out from the body side fixing member 1 by grasping the antenna main body 17 and pulling it up in an oblique direction. The antenna mounting member 2 removed from the body side fixing member 1 is stored in, for example, a trunk room. The cables connected to the connector 12 are omitted in the drawing.

On the other hand, in order to fix the antenna mounting member 2 with the antenna body 17 still mounted in the mounting frame body 4 of the body side fixing member 1, the protrusion 14 of the antenna mounting member 2 is mounted in the opposite manner to the above. When it is fitted in the frame body 4 and the operation lever 5 is rotated, the holding cam surface 6 presses the contact surface 16 formed on the projecting portion 14 to move the entire antenna mounting member 2 toward the back. The abutting surface 15 of the projecting portion 14 is pressed tightly against the abutting engaging surface 9 formed on the inner wall surface of the mounting frame body 4 on the inner side, and the antenna mounting member 2 is mounted inside the mounting frame body 4. It is in a locked state.

Next, in the body side fixing member 1 of the embodiment shown in FIGS. 8 to 14, one side edge is opened on the upper surface of the fixing plate 3 attached to the end edge portion of the trunk lid or the like in the automobile.

It is a thing.

According to this embodiment, as shown in FIG. 9, when the operation handle 18 is turned toward the front, the eccentricity suppressing roller 19 provided between the left and right arm portions of the mounting frame body 4 is rotated. As shown in FIG. 11, since a gap 20 is formed between the contact surface 16 of the protruding portion 14 protruding from the antenna mounting member 2 and the eccentricity suppressing roller 19, the antenna main body 17 is still attached in this state. The antenna mounting member 2 can be attached and detached with.

On the other hand, when the antenna mounting member 2 is locked while the antenna body 17 is still mounted, the operation handle 18 is rotated in the opposite direction to the position shown in FIG. The contact surface 16 of the protruding portion 14 is pressed downward, and a force that presses the entire antenna mounting member 2 toward the inner side of the mounting frame body 4 acts, so that the contact surface 15 of the protruding portion 14 becomes the mounting frame body. The antenna mounting member 2 is locked in the mounting frame body 4 of the body side fixing member 1 by tightly adhering to the abutting engagement surface 9 formed on the inner wall surface of the inner side of 4. (FIG. 10).

In addition, also in this embodiment, the abutting engagement surface 9 on the inner wall surface on the inner side of the mounting frame body 4 is a normal right downward tapered surface as shown in FIGS. A valley-shaped tapered surface having a V-shaped cross section as shown in FIG. 12 can be used. Furthermore, a curved concave groove surface as shown in FIG. 13 may be used. In this case, it goes without saying that the contact surface 15 of the protrusion 14 of the antenna mounting member 2 also has a shape capable of closely contacting with the contact engaging surface 9. Further, the shape of the contact surface 16 of the protrusion 14 can be changed to a shape as shown in FIGS. 12 to 14 other than the ordinary tapered surface, and any of these embodiments can be used. The eccentricity suppressing roller 19 allows the antenna mounting member 2 to be attached and detached.
