PURPOSE: A torque tube holder and a sunlight tracker using the same are provided to enable the twisting stress to be uniformly distributed on a cylindrical torque tube and to prevent the durability decrease due to the long use since a bearing supports the torque tube. CONSTITUTION: A torque tube holder comprises a cylindrical bearing(20), a cover(30), a flange(31), a half journal(50) and a post(70). The cylindrical bearing supports a cylindrical torque tube. The central part of the cover is formed in a cylinder shape and the cover supports the bearing. The flange is extended along the outer circumferential surface of the cover in a radial direction. The upper end of the half journal is formed in an arc shape and is fixed to the flange. The post supports the half journal. |
