(4) If the length of the pull-down wire 13 set at the time of shipment is too long for the window frame where the skylight blinds are actually installed, when the bottom rail 6 is moved toward the bottom box 3 to the maximum extent, Looseness occurs in the pulling wire 13. Even in such a case, the adjusting device 14 can easily and optimally tension the pull-down wire 13.
(5) If the length of the lifting wire 10 set at the time of shipment is too long for the window frame where the skylight blinds are actually installed, when the bottom rail 6 is moved toward the bottom box 3 to the maximum extent, Looseness occurs in the pulling wire 10. In such a case as well, the fixing rings 12a and 12b are unlocked and rotated, and the initial value of the winding amount of the pulling wire 10 wound around the winding shaft 8 is changed to lower the fixing ring 12a and 12b. The wire 13 can be easily and optimally tensioned.
(6) Since it is easy to adjust the lengths of the pulling wire 10 and the pulling wire 13, the length of the pulling wire 10 and the pulling wire 13 is set to be long at the time of shipment. Even if the actual window frame size is slightly larger than the specifications of the blinds for the building, it can be easily handled.
[0033]
The above embodiment can be modified as follows.
The fixing rings 17 a and 17 b that connect the pulling wire 13 may be positioned closer to the end of the winding shaft 8 than the fixing rings 12 a and 12 b that connect the pulling wire 10. In this case, the positions of the pulleys 11a to 11d and the code gates 15a, 15b, 16a, and 16b are changed in accordance with the change of the positions of the fixing rings 12a, 12b, 17a, and 17b, and the pull-down wire 13 is squared. It is necessary to stretch.
