Workability can be improved by eliminating the need for operation. Moreover, since the pair of protrusions 111 and 112 also serve as the reinforcing ribs of the sandwiching piece portion 11, no extra processing is performed on the sandwiching piece portion 11 in order to separately provide a detent for the bolt head, The fear of reducing the strength of the sandwiching piece portion 11 can be eliminated.

  Reinforcing ribs are also formed on the plane of the support portion 13. That is, a pair of protrusions 133 and 134 projecting downward along the longitudinal direction are formed at positions adjacent to the sandwiching piece parts 11 and 12 of the support part 13, and the pair of protrusions 133 and 134 are further connected. As described above, a pair of protrusions 135 and 136 are formed on the lower side perpendicular to the pair of protrusions 133 and 134. The pair of protrusions 135, 136 are arranged so as to sandwich the head of the bolt 15 inserted through the insertion hole 137 of the support portion 13, and have a hexagonal head so as to function as a detent for the head of the bolt 15. It is formed at an interval larger than the two-surface width of the portion and smaller than the diagonal distance.

  Accordingly, the protrusions 133, 134, 135, and 136 reinforce the plane of the support portion 13 and support the bolt 15 and the nut 16 when the bolt 15 and the nut 16 are fastened with the frame body 32 and the holding portion 14 of the solar panel 30 interposed therebetween. The strength required for the plane of the portion 13 can be ensured. Here, since each of the protrusions 133, 134, 135, 136 is formed to protrude below the plane of the support portion 13, the frame body 32 of the solar panel 30 is placed on the support portion 13. Each of the protrusions 133, 134, 135, 136 does not get in the way. In addition, since the pair of protrusions 135 and 136 function as a detent for the head of the bolt 15, when the nut 16 is screwed to the bolt 15, an operation for derotating the bolt 15 is unnecessary, and workability is improved. Can be improved.
