Kind Code:
B2
Abstract:
To provide a cord braking device for restricting the movement of cords that suspend shielding materials so that the shielding materials does not move at an unnecessarily high speed, which is capable of reducing the size thereof.SOLUTION: The cord braking device is configured to convert the movement of lifting code CD into a rotational movement so that part of one gear and part of the other gear are overlapped in a direction parallel to the direction of the rotation axis of a drive gear 35, an internal gear 41, a planetary gear 5, a fixed internal gear 23, and a sun gear 71 which are configured to transmit the rotation to the weight 7a in order. With this, since the diameter of the fixed internal gear 23 arranged on the outermost side can be reduced, the cord braking device 1 can be reduced in size.SELECTED DRAWING: Figure 30
