Abstract
With the object of a single worker being able to mount an automobile antenna, side plates of a board bracket 9 with fixing plate are inserted into a rectangular hole formed in the base portion 3 so that [the side plates] are located on the opposite side surfaces of a rectangular projecting portion projecting from the bottom surface of the base portion 3. Spring pieces 4a are formed on these side plates. When the cylindrical projecting portion 13 extending from the rectangular projecting portion is inserted in the mounting hole formed in the roof panel, the spring pieces 4a formed on the side plates pass through the mounting hole and engage with the back side thereof. The antenna body is thereby temporarily fixed to the roof panel and a worker can remove his or her hands from the antenna body. The worker then goes within the vehicle body, screws the fixing nut 2 onto the cylindrical projecting portion 13, and can thereby fix the automobile antenna on the roof panel.
