  • An extended flange portion 62 is provided to form a vertically extending surface. That is, the extension portion 61 and the extension flange portion 62 are T-shaped in a cross-sectional view.
  • spacers (abutment members) 63 are provided at both longitudinal ends of the extended portion 61 . The spacer 63 can be fixed to the fitting member 50 by providing the T-shaped extended portion 61 and the extended flange portion 62 when viewed in cross section.
  • the spacer 63 contacts the lower side surface 143 of the solar cell module 14b.
  • the fitting member 50 is positioned with respect to the solar cell module 14b, and the distance between the connection portion 53 and the solar cell module 14b can be appropriately maintained.
  • this spacer 63 is made of aluminum.
  • the carport according to the present invention is not limited to each embodiment described above.
  • the fitting member 20 is not limited to the shape of the above-described embodiment, and may have at least the lower flange portions 21, 51 and the connecting portions 23, 53.
  • the upper flange portion 22, 52 may not be included.
  • the lower flange portion 21 of the first embodiment can be modified as appropriate, such as by configuring to have the rising portion 54 of the second embodiment.
  • the seal member 34 and the spacer 63 are shown as the member that contacts the lower surface of the solar cell module 14b as the contact member, but the shape, installation position, and number of installation are the same. Not limited.
  • one spacer 63 is provided at each end in the longitudinal direction of the extension portion 61, but this is not a limitation, and the spacers 63 are spaced apart by a predetermined distance along the longitudinal direction of the extension portion 61. Three or more may be provided, or only one may be provided, for example, in the central portion with respect to the longitudinal direction of the extension portion 61 .
  • the seal member 34 may not be provided, or the seal members 34 may be provided on both surfaces of the connecting portion 23 .
  • the concave portion 133 of the upper rail 13 is configured to function as a rain gutter in the second direction, but it is not limited to this.
  • another member that functions as a rain gutter may be provided between the solar cell modules 14. FIG.
  • the cross-sectional shape of the extension portion 61 and the extension flange portion 62 is T-shaped, but it is not limited to this. Any shape may be used as long as the spacer 63 can be fixed.
