  • the portion 15D near the end portion of the horizontal cord 15B goes through the horizontal-cord insertion section 71 of the stationary member 70 and reaches the upper face side of the stationary member 70, and is connected to the vertical cord 15A similarly to the above-described first embodiment.
  • Fig.23(A) as a comparative example to this embodiment, if the stationary member 70 is fixed to the vertical cord 15A of the ladder cord 15, as shown in Fig.23(B) , if only one of the vertical cords 15A is raised and the stationary member 70 is inclined, the vicinity portion of a fixing portion 15E fixed to the stationary member 70 of the vertical cord 15A is bent.
  • a shielding reinforcing member 200 is attached so as to form an angle to bend downward with respect to the slat 11 substantially in the horizontal state.

  • Fig.17 it is supposed that the left side in the figure corresponds to the indoor side, while the right side to the outdoor side.
  • Fig.17(A) shows a state in which the slats 11 are substantially in parallel and opened. In this state, though the shielding reinforcing member 200 covers the upper half of the gap between the slats 11, the day light can be sufficiently ensured by the translucency.
  • the shielding reinforcing member 200 is also raised in conjunction with the rising rotation of the outdoor side of the slats 11 ( Fig.17(B) ), and when the closed state shown in Fig.17(C) appears, the member is located on the upper-end side of the slats 11, which does not obstruct the closed state.
  • the shielding reinforcing member 200 is also lowered in conjunction with the lowering rotation of the outdoor side of the slats 11, but, as shown in Fig.17(D) , the lower-end edge of the shielding reinforcing member 200 is brought into contact with the upper face of the slat 11 and brought into a half-closed state.

Moreover, on the bottom face of the recessed portion 31 is disposed the fitting projection 33 to be fitted in the fitting hole 23 on the narrow width section 22 side. Then, a side wall is not formed on the end edge of the recessed portion 31 to be an end edge portion of the connecting member 80 but the side edge is opened. By using such connecting member 80, the slats 11 can be easily connected to each other.
  • the connecting member 80 by applying the narrow width section 22 of the slat 11 on one side to the opened end edge of the recessed portion 31 in the connecting member 80 and moving the connecting member 80 toward the slat 11, the side edge of the narrow width section 22 of the slat 11 is smoothly inserted into the groove 32 of the connecting member 80. Furthermore, by moving the connecting member 80, the fitting projection 33 of the connecting member 80 is fitted in the fitting hole 23 of the narrow width section 22, and the connecting member 80 is attached to the narrow width section 22 of the slat 11 on the one side.
