Therefore, by adjusting the bolts 39, the angle of the head box 12 with respect to the stile 10 can be adjusted.

Next, to explain this blind 90 angle adjustment device,
In FIG. 11, 46 is the slat of the blind 9, 47
is a rutter cord that supports each slat 46. 4B
is the support shaft that supports the upper end of each ratter cord 47)
It is rotatably supported by a support member 49 fixed within the head hox 12. 50 is the support shaft 4B
The drive shaft is fitted into the support shaft 48 and cannot rotate relative to the support shaft 48, and cannot be moved relative to the support shaft 48 in the axial direction by means of a set screw (not shown) or the like screwed into the outer periphery of the support shaft 48.

Reference numeral 51 indicates three protrusions formed in a spiral shape on the outer circumferential surface of the central portion of the drive shaft 50, and reference numeral 52 indicates the same protrusions 5 at the protrusion 51 portion.
The transmission body is fitted to be slidable in the axial direction with respect to the drive shaft 50 while meshing with the head box 12. When the drive shaft 50 is rotated, the drive shaft 50 is rotated.

53 is a wire for moving the transmission body 52 left and right along the drive shaft 50, and its endless edge is supported by a pulley 54 rotatably supported at the other end of the head box 12, and the pulley 54 and the runner A transmission body 52 is connected in series to one of two wires 53 stretched in parallel between the two wires 53 and 11. The two wires 53 guided to the runner 11
As shown in the figure, it passes through the base end of the head box support frame 44 and is led to the rear of the runner 11. As shown in FIG. 3, the wire 53 led out to the rear of the runner 11 is guided inside the vertical stile 10 to the handle 17 position while being covered with a coiled outer cable 55, and then into the vertical analysis 10 at the handle 11 position. They are wound in opposite directions around a rotatably supported winding shaft 56. Then, the winding shaft 56
