Abstract
A roof apparatus includes a plurality of light collecting members, each having a pair of left and right vertical members, an upper horizontal member, a lower horizontal member, and a transparent plate. The upper horizontal members are disposed at a ridge side end of the vertical members, the lower horizontal members are disposed at an eaves side end of the vertical members, and the transparent plate is disposed on the inner periphery of the vertical members, the upper horizontal member, and the lower horizontal member. The light collecting members are connected in a slope direction of the roof, and the lower horizontal member has a transparent plate holding piece, a transparent plate contact wall, and a cover piece. The transparent plate holding piece is adapted to hold an eaves side end of the transparent plate. The transparent plate contact wall has a thickness which is smaller than the thickness of the transparent plate. The cover piece is adapted to cover an upper portion of the upper horizontal member of an adjacent eaves side light collecting member and extends from the upper end of the transparent plate contact wall.
