れスラットは閉鎖される。Then, the lead carriage 2' holds each of the holding members 18 to 20.
is pushed to the right end of the guide rail 1, and when the rotation shaft 5 is rotated, the worm 6 in each carriage 2, 2' is rotated, and the rotation of the worm causes the worm wheel 13 and the rotation support shaft to rotate. 12 is rotated, and accordingly, the bearing member 9, hook 10, coil spring 14, hook holder 16, and slat 11 are rotated together, and the locking protrusion 9b of the bearing member 9 is stopped by the stopper 8 on the support cylinder 7 side. Then, the rotation of the hook 10 and the slat 11 is stopped and the slat is closed.
スラット１１が停止した状態で回転軸５が同方向に回転

転される。When the rotating shaft 5 is rotated in the same direction with the slat 11 stopped, the worm wheel 13, which is pressed against the bearing member 9 by the coil spring 14, is rotated idly against the frictional resistance.
従って、ブラインドの組立時等、スラット１１の開放角
度が不揃の場合には、最後のスラットが閉鎖位置に回動
されるまで回動軸５を強制的に回転すればよい。Therefore, when the opening angles of the slats 11 are uneven when assembling a blind, etc., the rotation shaft 5 may be forcibly rotated until the last slat is rotated to the closed position.
一方、閉鎖状態のスラットを開放するには、前述した閉
鎖動作と全く逆の操作を行なえばよい。On the other hand, in order to open the closed slats, it is sufficient to perform an operation completely opposite to the above-described closing operation.

に対し被支承面１２ａがすべるようになっている。As described above, in the embodiment of the present invention, the upper part of the bearing member 9 has an inverted truncated conical bearing surface 9d, the worm wheel 13 is integrally formed, and the lower part of the worm wheel 13 of the rotary support shaft 12 has the shape of the support surface 9d. Supported surface 1 corresponding to bearing surface 9d
2a, the rotary support shaft 12 is rotatably supported on the support surface 9d of the bearing member 9 by its supported surface 12a, and the waist rotation support shaft 12 is biased against the bearing member 9 by a coil spring 14. , the bearing member 9 is rotated as the rotary support shaft 12 rotates due to friction between the support surface 9d and the supported surface 12a due to the biasing force of the coil spring 14, and the slat is rotated, and the locking protrusion 9b of the bearing member 9 is rotated. is engaged with the stopper 8 and the rotation of the coaxial bearing member 9 is prevented, the bearing surface 9d
The supported surface 12a is configured to slide against the support surface 12a.

することができる効果がある。Therefore, since the magnitude of the friction between the supporting surface 9d and the supported surface 12a is set by the urging force of the coil spring 14,
There is no need to increase the dimensional accuracy between the bearing surface 9d and the supported surface 12a, and the friction between them is
The simple structure consisting of a and the coil spring 14 has the advantage of being able to be set arbitrarily.
