In this configuration, there are 8 drive units) CKU motor C35
When power is applied to the + II source circuit through the *# connector GD and the motor C3 is driven, the gear G attached to the shaft (support)

In this way, the rotational torque of the main shaft (221, i.e., the rotating body 05) can be increased by sequentially connecting and meshing the plurality of drive units) C) 31° [with]',... on the main shaft. It becomes possible to rotationally drive an antenna device that is large and heavy.

Note that the present application is not limited to the above-mentioned embodiments, and the shape of the main casing (former), 4111 face opening 0, etc.
The number of gears constituting the gear reduction mechanism related to the drive unit, etc. may be changed as necessary.

In the above, all examples have been shown when the W motion motor C351k is provided as the drive source, but instead of kneading, there is an electromagnetic actuator whose movable part reciprocates, and a ratchet mechanism that converts the reciprocating motion of the movable part into rotational motion. It may be constituted by a crank mechanism, and in short, any means that drives the gear reduction mechanism C3B1 k rotation is sufficient.

As described above, according to the present application, a plurality of drive units (k) consisting of a drive section and a gear mechanism (k) can be increased or decreased as necessary for a rotary body that supports and rotates the rotary drive device (t) of the antenna rotation axis of the antenna device. Since the configuration is such that the rotary drive units with different drive torques are prepared for each J1rf or type of antenna device, it is not necessary to prepare a rotary drive unit with a different drive torque. It can be applied to antenna devices, and even when increasing or decreasing the number of antenna elements in an existing antenna device, the drive torque can be set to match the antenna device by simply increasing or decreasing the drive unit without removing and replacing the rotary drive device. In addition to being very economically advantageous, the drive unit can be attached and detached from the outside of the installed main casing, making it easy to handle and use.
