An antenna is adapted to be mounted on a vehicle body. An antenna base is formed with a first through hole. A first fixing screw is provided with a thread portion adapted to be inserted into a second through hole formed in the vehicle body via the first through hole, and a head portion continued from the thread portion and having a size larger than the second through hole. A receptacle is provided on the antenna base and receiving the head portion such that an axis of the first fixing screw is swingable relative to the vehicle body. A nut is adapted to be fitted with the thread portion so as to clamp the vehicle body together with the head portion.

Structure for mounting antenna base on vehicle body

A structure for mounting an antenna device on a first side of a panel body is disclosed. A first fixation member includes a first end having a first width, a second end, and a slit connecting the first end and the second end. A protrusion is protruded from the antenna device and fitted into the first end of the first fixation member. A second fixation member is fitted into the second end of the first fixation member while being coupled with the protrusion in a screwing manner. The first width is smaller than an aperture formed in the panel body when the protrusion and the second fixation member are in a first screwing position, so that the protrusion, the first fixation member and the second fixation member are allowed to pass through the aperture from the first side to a second side thereof. The slit is expanded such that the first end of the first fixation member is made to have a second width which is greater than the aperture when the protrusion and the second fixation member are in a second screwing position where the protrusion and the second fixation member are closed to each other than the first screwing position.

Antenna mounting structure

An antenna device is mounted on a vehicle body. A distal end of an antenna element is attached to an antenna base. The antenna base is provided with a conductive screw projection electrically connected with the antenna element and inserted into a hole formed in the vehicle body, and a first insulative member mounted on an outer face of the vehicle body to electrically insulate the screw projection from the vehicle body. A conductive washer is disposed inside the vehicle body such that the screw projection is inserted therethrough. A conductive nut is disposed inside the vehicle body to be screwed to the screw projection to form a conductive path from the antenna element and an electric equipment disposed inside the vehicle. A second insulative member is disposed inside the vehicle body to electrically insulate the screw projection from the washer, and to electrically insulate the nut from the washer.
