The main shaft 20 is rotatably supported by the main shaft support portion 12 of the base 10 to reciprocally rotate the horizontal shaft 30 installed on the main shaft 20 to the left and right. Referring to the drawings, the main shaft 20 is extended in length and is rotatably installed on the main shaft support portion 12 of the base 10. The main shaft 20 is provided with a horizontal axis support portion 21, such as a bearing arranged in a plurality in the longitudinal direction. The horizontal shaft support portion 21 is rotatably supported in a state in which the horizontal shaft 30 is disposed transversely with respect to the main shaft 20 in the width direction. One end of the main shaft 20 is provided with a motor support 23 for mounting the drive motor 51 of the horizontal drive means 50 for rotating the horizontal axis (30). The main shaft 20 is rotated reciprocally integrally with the horizontal axis 30 installed on the main shaft 20 by the main shaft drive means 40, accordingly the solar cell module panel (P) attached to the horizontal axis (30) ) Is rotated about the main shaft (20). In particular, since the plurality of horizontal shafts 30 are supported on the main shaft 20, several solar cell module panels P may be simultaneously rotated by the rotation of the main shaft 20.
