The drop-off prevention head 36 is formed at the root of a portion protruding from the antenna support portion of the vertical axis 13 with a rotating base plate. The width of the recessed portion 23 of the portion 20 (that is, the diameter of the circular hole portion in the center) is the annular recessed groove 37 having a diameter that is slightly the same as the diameter of the ring. By inserting the recessed portion 2 3 into the annular recessed groove 37, the peripheral edge portion of the recessed portion 23 of the rotating base plate portion 20 is brought into contact with the drop-off prevention head 36, and the rotating base portion 20 is aligned with the vertical axis 1 3. It can rotate freely and cannot prevent falling off in the direction of the axis, and it is also electrically connected together. The detachment prevention head 36 is completed by inserting the vertical shaft 1 3, the intermediate bearing fittings 14, and the insulating seat 22 into the detachment prevention hole portion 22a formed on the bottom surface of the insulating seat 22. The anti-falling treatment of the rotating base portion 20 with respect to the vertical axis 13 of the vertical axis 13 of the vertical axis 13 is performed.

A flange-shaped drop-off prevention head is formed at the front end of the longitudinal axis, and a U-shaped depression is formed from one side to the center of the rotating base portion of the intermediate bearing fitting, and the depression is fitted in the above. Under the head of the vertical axis, the above-mentioned insulating seat is used to prevent the vertical axis fitted in the recessed portion from falling off, so that the installation of the intermediate bearing fittings on the vertical axis is easy, and it can be easily assembled, and also serves as an insulating material. The number of parts is reduced. By forming a ring-shaped concave groove at the root of the front end of the vertical axis at the root of the portion protruding from the antenna support portion, the rotary base portion can be appropriately supported on the vertical axis, and no other base portion is required to prevent rotation. Falling parts can be miniaturized. A conductive spring material is used for the two bearing pieces integrally provided on the base end portion side of the antenna body. The two bearing pieces elastically hold the outer sides of the two horizontal shaft support pieces of the intermediate bearing fitting. When the antenna body is rotated with respect to the intermediate bearing component, the antenna body can be stopped from rotating at any position, and the antenna body can be properly electrically connected with the intermediate bearing component. The horizontal axis is formed of an insulating material, with a flange-shaped head on one end side, and a thinner cone on the front end side -15- (12) (12) 200406083 and The tapered portion on the proximal end side of the tapered portion is provided with an enlarged diameter portion for fitting the head of the horizontal axis through a horizontal axis through hole in each of the insulating bearing piece portions of the insulating sheath member. In addition, the locking section for anti-falling off can prevent the metal part from being exposed to the outside, and the antenna body can be properly pivoted to the intermediate bearing fitting.
