PROBLEM TO BE SOLVED: To enhance the workability when a vehicle antenna is attached to a vehicle body. SOLUTION: A bolt part 24 of a base 16 for supporting an antenna element is penetrated through a mount hole of a panel of the vehicle body. An amplifier case 46 for housing an amplifier board used to amplify a signal received by the antenna element is attached to the inside of the vehicle by screw-coupling a nut with a calking part 62 to the bolt part 24. The nut with a calking part 62 is turnably coupled in advance to an inward flange 50 of the amplifier case by expanding tips of a thin plate cylindrical calking part 64. Since the nut 62 is coupled to and integrated with the amplifier case 46, the workability at mounting is enhanced. COPYRIGHT: (C)2005,JPO&NCIPI
