Accordingly, the tilt cam 38 is always urged in the direction of arrow E shown in FIG. 8 by the urging force of the torsion coil spring 40 with the support case 32 as a fulcrum.

In the vicinity of the tilt cam 38, a guide roller 41 is rotatably supported by the support case 32,
A knurl is engraved on the peripheral surface of the guide roller 41. The elevating cord 10 inserted into the input shaft 12 is attached to the first guide shaft 42 attached to the support case 32 above the input shaft 12 and to the support case 32 on the side of the input shaft 12. The second guide shaft 43,
It is guided by the support member 5 in the head box 1 through the space between the tilt cam 38 and the guide roller 41.

The first guide shaft 42 is supported in a diagonal direction descending rearward, and the second guide shaft 43 is inclined in the same direction as the first guide shaft 42 and has a large inclination angle. Supported. The lifting code 10 is connected to the input shaft 12.
Is mounted on the upper side of the first guide shaft 42 from the front end, and then mounted on the lower side of the second guide shaft 43, and is guided between the tilt cam 38 and the guide roller 41.

The tilt cam 33 is moved by the tilt lever 33.
In a state in which the tilt cam 8 is not rotated, the tilt cam 38 is immovably pinched between the guide roller 41 and the guide roller 41 by the biasing force of the torsion coil spring 40 as shown in FIG. It is held in the position where it is worn. Further, when the tilt cam 38 is rotated by the tilt lever 33 against the urging force of the torsion coil spring 40, the gap between the tilt cam 38 and the guide roller 41 increases as shown in FIG. The sandwiched state of the lifting cord 10 is released.

When raising the slats 3, the cord equalizer 11 is operated and the lifting cord 10 is pulled out from the head box 1, so that the bottom rail 4 is raised and the slat 3 is raised. Then, when the code equalizer 11 is released, the lifting cord 10 is sandwiched between the tilt cam 38 and the guide roller 41 as shown in FIG. Therefore, it is possible to prevent the weight of the bottom rail 4 and the slat 3 from falling.

On the other hand, when lowering the slat 3,
When the operating rod 8 is pulled downward, the tilt case 31 is rotated via the input shaft 12 against the urging force of the torsion coil spring 36, and the state shown in FIG. Then, the tilt lever 33 comes into contact with the engagement piece 39 of the tilt cam 38,
The tilt cam 38 is rotated, and as shown in FIG. 14, the gap between the tilt cam 38 and the guide roller 41 is increased to release the clamped state of the elevating cord 10, and the bottom rail 4 and the slat 3 are moved by their own weight. Descended.

Therefore, the operation device of this embodiment can obtain the same functions and effects as those of the operation device of the first embodiment.
