PURPOSE:To give no effect of rotation to each other between the two double-laminated antennas, by using a planetary mechanism. CONSTITUTION:The planetary gear mechanism consists of the sun gears 6 and 7, planetary gears 8a and 8b plus shaft 8c. The rotary part 4 is provided at the upper part of the basement 5 via the bearing 11, and the antenna 1 is attached to the part 4. In addition, the fixed rest 2 is provided at the upper part of the part 4 via the bearing 10, and the antenna 3 is installed on the rest 2. The planetary gears 8b and 8a engage the sun gears 7 and 6 provided to the basement 5 and the rest 2, respectively and then connected with each other by the shaft 8c. At the same time, the pinion 8 consisting of the three points of the gears 8a and 8b plus the shaft 8c is supported by the bearing 9 provided at the part 4. |
