The pedestal 123 extends downward from the lower edge of the table body 121 and is movably supported on the base frame 130. A first bearing (125) is installed between the turntable (120) and the lamp post (20).

The base frame 130 is fixed to the column 20 and supports the turntable 120 such that the turntable 120 can be reciprocated at a predetermined angle around the column 20. [ The base frame 130 preferably has a disc structure.

The altitude varying unit 140 is for adjusting the elevation angle of the solar cell panel 10 by adjusting the angle of the rotating frame 110 on the turntable 120 up and down. The elevation angle adjusting unit 140 includes an elevation guide bar 141 vertically installed at a substantially central portion of the turntable 120, a pulley driving motor 143 installed at the turntable 120, a pulley driving motor 143, A wire 147 connected to the drive pulley 145 at one end and connected to the rotary frame 110 at the other end and a wire 147 connected to the upper end of the elevation guide bar 111, And a second bearing 149 for rotatably supporting the upper end of the elevation guide bar 111 with respect to the column 20.

Further, when adjusting the elevation angle of the solar cell panel 10, since the wire 147 is operated by a so-called pulley method in which the wire 147 is pulled or loosened, it can be operated smoothly as compared with a conventional operation using an actuator or the like. Therefore, the stability can be improved by minimizing vibration or noise during the altitude angle control.

In addition, by having a simple structure in which wires are wound or unwound by using a single pulley drive motor, the cost and weight can be reduced as compared with the prior art. Therefore, it is possible to reduce the operating load and maintain a stable posture against strong winds, thereby reducing the cost of driving and maintaining.
